No. 15/830,661 entitled “SYSTEM AND METHODS FOR USING KINETIC ENERGY TO ASSIGN COINS EXCHANGED FOR CRYPTOCURRENCY,” filed Dec. 4, 2017, The above referenced application is hereby incorporated by reference in its entirety for all purposes. 
    
    
     BACKGROUND 
     Field of the Art 
     The present invention relates to an apparatus for tracking and incentivizing user activity. 
     Discussion of the State of the Art 
     Cryptocurrency is a digital or virtual currency that is encrypted or secured using cryptography. Cryptography refers to the use of encryption techniques to secure and verify the transfer of the transfer of transactions. The cryptocurrency market is growing rapidly and attracting savings for new investors every day. 
     The first coin in the world, Bitcoin, has reached unimaginable values and has also dragged other cryptocurrencies to success. Bitcoin is a cryptocurrency which transacts on a secure decentralized ledger. The decentralized ledger is distributed throughout an open network. The ledger is known as the blockchain allowing participants in the network to transact using Bitcoin without the need of a trusted third party, such as a bank. In other words, blockchain is directed to the underlying technology for cryptocurrencies—it is the whole ledger. The blockchain contains all the transactions, or “blocks”, completed since the beginning of the ledger. 
     A blockchain is a digitized, decentralized, public ledger of all cryptocurrency transactions. Constantly growing as ‘completed’ blocks (the most recent transactions) are recorded and added to it in chronological order, it allows market participants to keep track of digital currency transactions without central recordkeeping. Each node (a computer connected to the network) gets a copy of the blockchain, which is downloaded automatically. All confirmed transactions are included in the blockchain and available to the user through a wallet application. The wallet application communicates a user&#39;s cryptocurrency balance, history of transactions, and verifies cryptocurrencies owned by the user. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending Bitcoins that are owned by the spender. 
     A cryptocurrency wallet is a software program or application that stores private and public keys and interacts with various blockchains to enable users to send and receive digital currency and monitor their balance. Digital wallets are required to use cryptocurrency. Cryptocurrencies don&#39;t get stored in any single location or exist anywhere in any physical form. All that exists are records of transactions, or “blocks”, stored on the blockchain. To be able to spend those coins and unlock the funds, the private key stored in the wallet must match the public address the currency is assigned to. Again, there is no actual exchange of tangible money. The transaction is signified merely by a transaction record, i.e., “block”, on the blockchain and a change in balance in the cryptocurrency wallet. 
     The most common categorization of cryptocurrency is known as coins or tokens. The term “coin” refers to Bitcoin as well as other alternative coins such as Centurion, Ethereum, Namecoin, Peercoin, Ripple, Litecoin, and Dogecoin. The term “token” refers to a particular asset or utility, that usually resides on top of another blockchain. Tokens can represent basically any assets that are fungible and tradeable, from commodities to loyalty points to even other cryptocurrencies. For purposes of this application, the term “coin” and “token” are used interchangeably with the understanding that each may operate on their own separate blockchain or operate on top of a blockchain that facilitates the creation of decentralized applications. 
     The integrity and the chronological order of the blockchain are enforced with cryptography. Separately, it also prevents double spending, stealing and the forging of value. The financial services industry, beyond looking at the potential of cryptocurrencies, has recently turned its attention to using the blockchain ledger separate from Bitcoin or other cryptocurrencies and applying it to other processes and products. 
     Blockchain systems are global state systems wherein the global state is stored across a distributed number of devices. These blockchain systems typically operate on cryptocurrency networks such as Bitcoin, Ripple, Namecoin, among others. A combination of public/private key cryptography and hash chains provides a mechanism to store arbitrary secure states as a single ledger—the blockchain—held at all distributed nodes. Nodes update their local state based on “proof of work” hashing algorithms applied to the system. These systems provide a secure mechanism for establishing shared common ground across many devices. 
     The cryptocurrencies to be produced require “mining”, a system that, thanks to the use of hardware devices, and with specific algorithms, can allocate coins produced in blocks, sharing them between users, based on a power of calculation. 
     The most common cryptocurrency allocation systems to mine cryptocurrencies depends on a “proof of work” system. A “proof of work” is a piece of data which is difficult (costly, time-consuming) to produce but easy for others to verify and which satisfies certain requirements. Producing a proof of work can be a random process with low probability so that a lot of trial and error is required on average before a valid proof of work is generated. Bitcoin uses the Hashcash proof of work system that limits email spam and denial-of-service attacks, and forms part of the mining algorithm. 
     Since most cryptocurrencies use ever more powerful machines, the energy consumed to produce cryptocurrencies increases each day. To date, in an interesting but still limited market, current consumption to mine Bitcoin is soon very likely to be closed to the whole state of Denmark. 
     Also, some Internet Technology (IT) corporations have created powerful device (like Asics and Baikal) that are able to outperform any other device in terms of hash power. 
     This reduces the chances for every user that has one Personal Computer (PC) to mine most well-known and appreciated cryptocurrencies. 
     This fact indicates that if this market becomes bigger, the energy consumptions needed to produce cryptocurrencies may become very high and totally adverse to the ecosystem. 
     It is true that today, there are other systems for allocating cryptocurrencies in alternative ways, which are eco-friendlier. One of these is to pre-mine the coins. In this case the coins are produced wholly or partially from the beginning. 
     But this particular case presents several disadvantages. Coins have been overtaken frightening users and investors because they are centralized, e.g., owners of coins can buy them from the market cashing down prices. Non-minable coins are often launched through an Initial Coin Offering (ICO), a fundraising system that is not regulated and can create many problems with no guarantees for people who buy cryptocurrencies. 
     Another issue in this industry is that the distribution of cryptocurrencies is far from a decentralization possession. Like most aspects of finance, a high percentage of wealth is in the hands of a small percentage of people. 
     In addition, the only cryptocurrency allocation system today occurs with electronic, static means requiring a standard power supply (110-220 v). 
     Electronic cryptocurrency allocation systems do not promote physical wellness. 
     Thus, there is a need for a system and methods which could allow mobile phones to mine coins using light algorithms, saving energy. However, at present, smart phone hardware is not yet powerful enough to make this possible. 
     There is also a need for a system that allows a distribution of coins that is eco-sustainable. 
     There is another need for a system that uses an alternative energy source to allocate and distribute coins. 
     There is a further need for a truly decentralized system that does not allow only a few privileged users to own most of the cryptocurrencies themselves. 
     There&#39;s a need to create a cryptocurrency decentralized assignment and distribution process which does not use a power supplied system, but involves a mobile power supply with external sources like lithium ion or solar cell or any renewable energy source. 
     There is also a need for methods where the cryptocurrency assignment is correlated to activities promoting human health. 
     SUMMARY 
     This disclosure is not limited to the particular systems, and methodologies described herein, as there can be multiple possible embodiments of the present disclosure which are not expressly illustrated. It is also understood that the terminology used in the description is for describing the versions or embodiments only, and is not intended to limit the scope of the invention. 
     The present invention is for an apparatus for tracking and incentivizing user activity, wherein the apparatus is comprised of a a display device; a bodily function sensor that provides output data comprising information about bodily function of a user; and one or more processors configured to: obtain bodily function data from the bodily function sensor; obtain physical exertion data from a wearable device that is configured to provide physical exertion data when the wearable device is worn by the user, the physical exertion data comprising information about physiological activity that the user is engaged in; identify a time period wherein obtained bodily function data and the obtained physical exertion data is obtained over a same period of time; determine whether the bodily function data and the physical exertion data within the identified time period indicate that the user is engaged in one or more known activities during the identified time period; determine whether the bodily function data and the physical exertion data within the identified time period are both associated with the user; interface with a crypto coin assignment system to identify the amount of crypto coins to assign to the user if the bodily function data and physical exertion data within the identified time period is associated with a known activity and if both data sets are associated with the user and within a threshold range; and interface with a distributed ledger system to determine if an amount associated with the assigned crypto coins are recorded in a distributed ledger system. 
     The wearable device may be comprised of a wrist-worn wearable device or an arm-worn wearable device. The wearable device may be comprised of at least one of a heart rate monitor, a wearable glove, and/or eyeglasses. The bodily function sensor is comprised of at least one of a heart rate sensor, a blood pressure sensor, a pulse rate sensor, a blood oxygen level sensor, a perspiration sensor, an accelerometer, a gyroscope, a magnetometer, a global positioning system sensor, pedometer, or a pressure sensor. In one embodiment, determining whether the bodily function data and the physical exertion data are both associated with the user is comprised of matching the at least one of the heart rate, the blood pressure, the pulse rate, the blood oxygen level, or the amount of measured perspiration, to a nominal reference value associated with the physical exertion activity. The apparatus further comprising determining whether a separation distance between the bodily function sensor and the wearable device is within a threshold separation distance. The apparatus further comprising a transducer that translates the physical exertion activity performed by the user to an electrical power output; and a power management system that conditions the electrical power output to at least one of operate a component in the apparatus, charge a rechargeable battery in the apparatus, or store charge in an electrical power storage device in the apparatus. The one or more processors may be further configured to generate a physiological metric based on data provided by one or more of the bodily function sensor and the wearable device. The bodily function sensor and the wearable device may be comprised of a motion sensor, and/or the physiological metric comprises steps walked or run, stairs climbed, or calories burned. The one or more of the bodily function sensor and the wearable device may be comprised a heart rate sensor, and/or the physiological metric comprises a heart rate. 
     The present invention provides a system and methods that assigns cryptocurrencies based on kinetic energy produced by human movement, allowing decentralized distribution of the cryptocurrencies. The invention also contemplates harvesting the kinetic energy associated with the human movement and using it thereby saving electrical energy such as electricity power, battery power and the like. 
     Although the invention is discussed with respect to kinetic energy according to movement of a user, it is also contemplated that the invention may be directed to and/or include other parameters such as consumed calories, altitude, geographical terrain, food choices, time of eating, type of mobile device used, type of sensors used, etc. 
     The present invention provides a system and methods for assigning one or more cryptocurrencies in time intervals by using human physical power via a blockchain distributed network. One or more sensors are used to detect human movement. The sensors are operatively coupled to a mobile device that includes a mobile application. Human power shares are calculated from the sensor data related to movement of a user. A human power share is the kinetic energy recorded as sensor data and multiplied by a predetermined power share value. 
     Human power shares are converted into coins that are exchanged to cryptocurrency using a blockchain server. The data server receives the human power shares calculated by the mobile application of the mobile device and assigns coins. However, it is contemplated that the data server receives the sensor data related to movement and calculates the human power shares. The coins are sent to a blockchain server that exchanges the coins to cryptocurrency. The blockchain server sends the cryptocurrency to the user&#39;s wallet via a wallet application. The wallet application is accessible through the user&#39;s mobile device, for example on the display unit. 
     The invention comprises a mobile device interacting over a network with one or more sensors, a data server, and a blockchain server. The sensors may be built-in the mobile device or external to, but in communication with, the mobile device. The data server includes a software program to calculate a number of coins assigned that are exchanged to cryptocurrency through a blockchain server. Although the invention is discussed in reference to the data server assigning a number of coins, it contemplated any server and/or device such as the mobile device, alone or in combination, may be used to determine the number of coins assigned. 
     The system and methods of the invention may operate over a global area network (GAN), such as the Internet, a wide area network (WAN), a local area network (LAN), or any other type of network, or combination of networks. It is contemplated that short range communication such as that between the sensors and mobile device may be accomplished through infrared (IR), radio frequency (RF), Bluetooth technology, near field communication (NFC), ultraband or Zigbee. 
     According to the invention, a mobile device may generate data using sensors with or without a network connection. If a network connection is not available, data can be stored and transmitted upon availability of a working connection. 
     It is also contemplated that invention may incorporate penalties or rewards, for example adding coins or deducting coins used to exchange for cryptocurrency. Penalties or rewards may be related to a “task” or an “assignment”, i.e., action items a user must perform or complete, such as within a predefined interval of time. For example, a display unit of a mobile device can display an assignment as provided by the data server. An example of assignment may be for the user to maintain a body health parameter within a threshold level. Body health parameters may include, for example, heart pressure level, sugar level, blood pressure level, weight, body mass index value, body fat percentage, etc. Another example may be a task requiring physical activity such as dancing, exercise, visiting interesting places such as a particular store or shopping mall, use of renewable energy sources, etc. Yet another example may be penalties or rewards for a particular type of mobile device used or specific type of sensor. As an example, 10 additional coins may be transferred to a user&#39;s wallet application if a pressure sensor is used. Another example may be additional coins assigned when a smart watch is used that reduces detection errors versus a smart phone. Another example may be coins added or deducted from a user&#39;s wallet application based on results of a light sensor, e.g., whether a user&#39;s movement is during the daytime or nighttime. In certain embodiments, the invention may utilize a user&#39;s silhouette, particularly the physical form. As an example, a user&#39;s silhouette is compared at two different time periods. If the silhouette improved (i.e., smaller), additional coins may be assigned. Hence the invention improves physical well-being by promoting physical activity such as walking. 
     According to the invention, completion of an assignment can be verified. For example, verification may be based on the amount of human power shares generated for the assignment. If a task requires production of at least 10 human power shares and the user only produces 5, the task remains incomplete which may cause 10 coins to be deducted from a user&#39;s wallet application. 
     Detection errors may also be reduced through a sensor that detects a distance between the user and the mobile device. Detection sensors can be internal or external to the mobile device and used to determine physical contact between the device and the human body. 
     It is also contemplated that errors caused by non-human motion can be reduced by validating the movement detected based on perceived parameters of a user such as heartbeat, breath or temperature. In certain embodiments, the invention includes software and or device filters that exclude virtuous manipulations by users, or automatic replacement of detection errors of human movements. For example, speed per second can be measured, deviation from an axis used with a gyroscope and other parameters, a number of steps and displacements relative to an axis in a specific time period, continuity of working hours, or other statistical factors. More specifically, motion detection may only be considered valid if sweat sensors detect sweat during an exercise assignment, tactile sensors are used, or if human presence is detected with passive infrared (PIR) sensors. 
     The present invention may also include an advertisement server. The advertisement server facilitates targeted advertising based on the sensor data, for example the type of movement made by a user. The advertisement server is adapted to access the database of data server. Based on the data accessed, the advertisement server is selects and sends a targeted advertisement—text, image, video, audio—to the user mobile device. Targeted advertisements may be determined based on a task or assignment, type of sensors used, data recorded, type of human movement, etc. For example, users that run or jog receive sporting goods advertisements whereas tireless walkers receive advertisements on wearable tracking devices. This information can then be used to create a detailed user profile. 
     It is also contemplated that a user may have priority in a product or service purchase system as determined by human power shares assigned over a period of time. Instead of exchanging for cryptocurrency, the coins may be exchanged for a product or service or for vouchers redeemable for a product or service. Furthermore, priority in purchasing the product at a favorable price may be determined. For example, a product typically valued at 100 coins is offered at 50 coins to those users that achieve a minimum number of power shares during a specified time frame, i.e., 100 power shares in 60 minutes. It is also contemplated that priority in a product or service purchase system may be associated with an auction forum in which the assigned coins can be used to bid on products or services. 
     It is also contemplated that a percentage of assigned coins may be automatically allocated to one or more entities, such as a humanitarian organization. 
     One important aspect of the invention is that it provides a decentralized system. The invention also provides a decentralized system that operates with a very low or no consumption of current. Additionally, the decentralized system may be used without having to supply personal data that could compromise the security of system. 
     The invention is also adaptable to work with any existing or new cryptocurrency network. 
     It is contemplated that system and methods of the invention includes administration that may directed to any agreement including the type and number of coins assigned. For example, each user may have a certain share of coins, which can be exchanged for any cryptocurrency subject to the agreement. 
     It is contemplated the invention promotes cryptocurrency education, i.e., users may learn about coins, how they may be exchanged for cryptocurrency, details of the exchange market, etc. 
     Another important aspect of the invention is that kinetic energy of a user can be stored and used to extend the battery life of a mobile device. Kinetic energy recorded by sensors may be transmitted to a server using mobile batter power or a power supply of renewable energy. 
     The invention further contemplates a distribution policy that considers time constraints to ensure decentralization and a degree of casualty typical of the current mining system. With mining “proof of work”, coin allocation is based on the power of the device used and the random process used to produce the “proof of work”. 
     It is also contemplated that the invention may provide a comparison of the energy savings between the power required to produce coins using the typical proof of work mining system versus the power required to assign coins according to the methods of the present invention. 
     According to an embodiment of the invention, the coin assignment may be performed according to a relationship between any of the following: randomness (number of movements in a period), effect (personal number of movements developed by a user in a fraction of time), and movement itself (type of motion that can result from running, jogging, walking, swimming, and any sport) as detected by one or more sensors. 
     Moreover, the invention enables a variety of statistics to be gathered regarding the assigned coins and the exchange of the coins into cryptocurrency. These statistics may be valuable for economic analysis and consumer trends. 
     The system and methods of the invention may also include a chat forum for communication between the users thereby creating a community of users. 
     The system and methods of the invention may also protect the environment from disproportionate energy consumption. As an example, an energy savings value equivalent to the production and assignment of crypto coins can be communicated to a user through a display unit thereby encouraging the user to value energy consumption. 
     Although the invention is discussed with respect to kinetic energy resultant from human movement, kinetic energy may also include that produced by acoustic noise and low-frequency vibrations. One practical example includes a battery-less remote control unit built-in the mobile device or remotely connected to mobile device. Power is harvested from the force that a user applies when pressing a button. The harvested energy may power a low-power circuit and transmit an infrared or wireless radio signal. 
     Another practical example includes pressure sensors for car tires remotely connected to the mobile device: piezoelectric energy harvesting sensors are located on or near a car tire in order to monitor pressure and transmit the information to a mobile device or a dashboard for the driver. In this example, a user is assigned coins not based on kinetic energy, but based on values of tire pressure which may maintain road safety. 
     Yet another practical example may include piezoelectric floor tiles: kinetic energy from people walking on the floor is converted to electrical power that can be used for essential services such as display systems, emergency lighting, powering ticket gates, and more. 
     The invention provides many technical results. One technical result of the invention is directed to obtaining by means of a mobile device cryptocurrencies using a decentralized system with a very low consumption or no consumption of current/power. 
     Another technical result is directed to receiving cryptocurrency payments automatically without having to supply personal data that could compromise security of the system. 
     Another technical result is directed to generating data using sensors with or without a network connection, e.g., if a network connection is not available data can be stored and later sent to a server (data or blockchain) when a network connection becomes available. It is also contemplated all data of the invention may be encrypted. 
     Another technical result is directed to utilizing energy to extend the battery life of a mobile device. 
     Another technical result is directed to generating coins, utilizing data for statistical purposes including data directed to a true decentralized system and methods that secures anonymity of users. Although location data may be known, personal data is obscured. This is an important aspect of the invention since currently a truly secure decentralized system and methods is not currently available for any cryptocurrency, which may be important in the future for the cryptocurrency exchange market and financial institutions that may only accept cryptocurrencies proven to be both secure and decentralized. 
     The invention and its attributes and advantages may be further understood and appreciated with reference to the detailed description below of one contemplated embodiment, taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION 
     According to the invention, a smart phone application and smart phone sensors are used to convert human movement into human power shares. Human power shares may also be determined by the data server. Kinetic energy in the form of human movement data is recorded from the sensors during specified time intervals. The data from all devices is summed together to determine a proper calculation of a user&#39;s power shares. Depending on the number of a user&#39;s power shares, one or more coins are assigned. Then the coins are transferred to a user&#39;s wallet directly from the blockchain for exchange into cryptocurrency.

     The power management unit  130  harvests kinetic energy recorded by the one or more sensors  160 , which may be used, for example, as electrical energy to increase the life of a mobile device battery. Harvesting kinetic energy takes different forms based on the source, amount, and type of energy being converted to electrical energy. Sources of energy may include heat, light, movement or vibration. As an example, Piezoelectric transducers produce electricity when kinetic energy is detected from vibrations, movements, sounds, heat waves or motor bearing noise such as from aircraft wings and other sources. The sensor converts the kinetic energy from vibrations or human movement into an AC output voltage and transmits it to the power management unit  130 . The energy is then rectified, regulated, and stored in the mobile battery or a thin film battery or a super capacitor. 
     As mentioned above, one or more sensors  160  may be utilized to assign coins that are exchanged for cryptocurrency. As shown more specifically in  FIG. 4A , a sensor  160  is shown as a heart rate monitor  162  worn as a belt around the torso that records heart beats of a user.  FIG. 4B  illustrates a sensor  160  in the form of wearable gloves  164  with tactile sensors to capture data related to hand movement of the user.  FIG. 4C  illustrates eye glasses  166  including a PIR sensor to measure infrared (IR) light radiating from objects in its field of view, a gyroscope, an accelerometer, a magnetometer and pulse sensor. 
       FIG. 5  illustrates a flow chart of a method  210  for exchanging coins assigned based on kinetic energy to cryptocurrency according to an embodiment of the invention. 
     At step  240 , data from one or more users is recorded by sensors during a time frame. The data may be detected from any form of movement such as a number of steps while walking or jogging, a handshake, a number of weight repetitions, etc. The time frame may be any contemplated value and is a predetermined value, e.g., 10 minutes, 24 hours, 1 week, 2 months, 5 years, etc. The number of coins assigned is calculated at step  250  described more fully in  FIG. 6 . According to the invention, the number of coins assigned may be calculated by either the mobile device, the data server, or the blockchain server, each alone or in combination. At step  260 , the number of coins assigned is transferred to the blockchain server. The number of coins is then exchanged for cryptocurrency at step  270 . At step  280 , the cryptocurrency is added to a user&#39;s wallet application. 
       FIG. 6  illustrates a flow chart of a method  250  for calculating the number of coins assigned based on kinetic energy of a user. At step  251  a predetermined quantity of crypto coins to disperse during a given time period is provided. The predetermined quantity of crypto coins can be any contemplated quantity and can change depending on coin number specifications that are included in code programming. 
     The number predetermined coins to be dispersed within a particular time frame can be determined based on a number of available users or the value of the cryptocurrency itself as evidenced by a cryptocurrency exchange market. For example, a market value such as that from a cryptocurrency exchange can be referenced prior to providing the predetermined quantity of crypto coins at step  251 . As an example, if the value of a particular cryptocurrency is greater than 0.20 cents, the quantity of coins to be dispersed may be reduced by 10% or if the particular cryptocurrency is less than 0.10 cents, the quantity of coins to dispersed may be increased by 10%. In this case, the cryptocurrency assignment is correlated to the market value. It is also contemplated that the quantity of crypto coins dispersed in the time frame may change according to a threshold value such as when either the total human power shares or the quantity of the crypto coins dispersed surpasses the threshold value. It is also contemplated that the number of crypto coins distributed in the time frame may change according to a total number of power shares generated by movements of all users. For example, the predetermined number of coins for distribution increases when the number of power shares exceed a threshold number, or the predetermined number of coins decreases when the threshold number is not met. 
     At step  253 , the data of kinetic energy of a user is received and converted into individual human power shares. Human power shares are kinetic energy recorded as sensor data and multiplied by a predetermined power share value. The share value may be any contemplated value as coded in the system, for example, 0.01 for every step, 0.001, or 0.0000001 to name a few. It is contemplated that the share value may also depend on the cryptocurrency and its conversion factor as determined by a coin administrator as agreed with coin founders, for example, 0.001 for Bitcoin, 0.01 for Centurion, etc. Hence a user may exchange crypto coins into any cryptocurrency. So if a user gets 100 coins, he or she could exchange them for a certain number based on the type of cryptocurrency desired, e.g. 50 in Bitcoin, 10 in Centurion, 20 in Ethereum. 
     At step  255  the total number of human power shares by all users is computed. A multiplier value is then determined at step  257  by dividing the predetermined quantity of crypto coins by the total number of human power shares. At step  259 , individual human power shares are multiplied by the multiplier value to calculate the number of coins assigned. 
     To illustrate by way of example, suppose the predetermined quantity of crypto coins to be assigned in a time frame is coded in the system as 1000 crypto coins assigned every 10 minutes. Suppose one user produces 10 human power shares in a 10-minute time frame derived from a 0.001 predetermined share value for one step or single movement (as coded in the system). Within the set time period, there are 50 users who produced a total of 500 human power shares. Hence 1000 cryptocurrencies are divided by 500, to reach a multiplier of 2. The user that produced 10 human power shares in the 10 minutes time frame will receive 20 crypto coins, which equals the multiplication between the individual human power shares and the multiplier. 
       FIGS. 7A through 7D  each illustrate a screen shot of the display unit of the mobile application.  FIG. 7A  illustrates a graphical representation of a chart  182  illustrating a total number of cryptocurrencies exchanged for coins, a total number of steps, calories burned, and a summary illustrated in the form of a bar chart.  FIG. 7B  illustrates a graphical representation of a chart  184  illustrating energy shares of one or more users based on daily activities such as walking.

FIG. 7D  illustrates a graphical representation of a chart  188  illustrating a map of all users contributing to the total number of human power shares. 
       FIG. 8  illustrates an exemplary energy harvesting circuit, which can harvest kinetic energy to increase the life of the battery of a mobile device and may further contribute to saving energy when distributing cryptocurrencies according to the invention. In some embodiment of the present invention, the kinetic energy data is saved in the memory unit of the mobile device and communicated to the data server. If there is no communication link between the network and mobile device, it is contemplated the data is stored in the memory unit and transmitted automatically to the server when a connection becomes available. 
       FIG. 9  illustrates a block diagram of a system including an advertisement server according to an embodiment of the invention. According to an embodiment of the invention, advertisement server  500  is adapted to access the database  201  of data server  200 . Based on the data accessed, the advertisement server  500  is selects and sends a targeted advertisement—text, image, video, audio—to the user mobile device  100  ( FIG. 3 ). It is also contemplated that the advertisement server  500  can create and add to the database  201  of the data server  200  a task or assignment. Human power shares in relation to the advertisement task are determined and sent to the data server. Coins are assigned and exchanged for cryptocurrency available in a user&#39;s wallet application. 
     While the disclosure is susceptible to various modifications and alternative forms, specific exemplary embodiments of the invention have been shown by way of example in the drawings and have been described in detail. It should be understood, however, that there is no intent to limit the disclosure to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the disclosure as defined by the appended claims. 
     More particularly, other embodiments may be directed at addressing various aspects of other needs indicated in the description above, such as, for example, the following needs: 
     Electronic cryptocurrency allocation systems do not promote physical wellness. 
     Thus, there is a need for a system and methods which could allow mobile phones to mine coins using light algorithms, saving energy. However, at present, smart phone hardware is not yet powerful enough to make this possible. 
     There is also a need for a system that allows a distribution of coins that is eco-sustainable. 
     There is another need for a system that uses an alternative energy source to allocate and distribute coins. 
     There is a further need for a truly decentralized system that does not allow only a few privileged users to own most of the cryptocurrencies themselves. 
     There&#39;s a need to create a cryptocurrency decentralized assignment and distribution process which does not use a power supplied system, but involves a mobile power supply with external sources like lithium ion or solar cell or any renewable energy source. 
     There is also a need for methods where the cryptocurrency assignment is correlated to activities promoting human health. 
     At least some of these needs may be met by another exemplary embodiment of the invention, which pertains to a system configured to reward and/or penalize an individual based on assessing a physical exertion activity performed by the individual. The reward can be provided in the form of cryptocurrency that is generated by a user device. In some cases, the cryptocurrency may be generated independently by the user device (a smartphone, a tablet computer, a laptop computer, etc.) In some other cases, the user device may generate the cryptocurrency in cooperation with one or more computers such as, for example, the data server  200  and the blockchain server  300  described above. Various factors such as, for example, the value of the cryptocurrency, the type of cryptocurrency, the manner in which the cryptocurrency is awarded, the form and/or structure in which the cryptocurrency is deposited and/or stored and/or distributed, the time when awarded, etc. etc. can vary from one implementation to another implementation in accordance with the invention. 
     The exemplary system that is configured to reward and/or penalize an individual based on assessing a physical exertion activity performed by the individual can include a first sensor, a second sensor, and a user device. The first sensor produces a first metric, which may be based on sensing a physical exertion activity performed by an entity. In a first scenario, the entity is a human being who is performing one or more of various types of physical exertion activities such as, for example, working out in a gymnasium. The workout can include, for example, muscle building exercises, body toning exercises, stamina-building exercises, and cardio exercises. The first metric can be provided in various forms in accordance with the type of physical exertion activity. For example, the first metric can be a numerical value that quantifies a physical exertion activity involving repetitive motions of one or more limbs. A pushup routine may be quantified by “x” number of pushups performed by the individual. The pushup routine may be further quantified by a time parameter that indicates an amount of time taken by the individual to perform the “x” number of pushups (30 minutes, for example). As another example, the first metric can be another type of numerical value that quantifies a physical exertion activity involving a muscle building exercise. The first metric in this case, can be, for example, a weight of a dumbbell, a barbell, a kettle ball or a medicine ball lifted by the individual. The muscle building exercise may be further quantified by a repetition parameter that indicates the number of times a certain weight was lifted by the individual (100 kgs, 25 times, for example) and/or a time parameter that indicates an amount of time taken by the individual to perform the muscle building exercise. The first sensor can produce the first metric continuously, repetitively, or intermittently at various instants in time. In one application, the first metric may be produced after the individual has completed performing the physical exertion activity. In another application, the first metric may be produced in real time as the individual is performing the physical exertion activity, such as, for example, to indicate a rate at which a physical exertion activity is being carried out. The individual may be fresh at a first instant in time and the rate may be high (10 pushups in 1 minute, for example). At a later instant in time, the individual may be tired and the rate may be lower (5 pushups in 2 minutes, for example). 
     In a second scenario, an unethical individual may try to cheat the system by using an object to simulate the physical exertion activity. For example, the unethical individual may attach the first sensor (which may be provided inside a wearable device such as a Fitbit®, for example) to the tail of his pet dog or attach it to a washing machine during a wash cycle. The system is configured to detect such cheating activities. In one application, the cheating activity may be detected by using the second sensor that produces a second metric based on monitoring a bodily function of an individual. In an example application, the second sensor can be provided in various forms such as for example, a wearable device (an activity tracker device, for example), a heart rate monitor such as the heart rate monitor  162  worn as a belt around the torso (illustrated in  FIG. 4A  and described above), wearable gloves  164  (illustrated in  FIG. 4B  and described above), or eye glasses  166  including a PIR sensor (illustrated in  FIG. 4B  and described above). 
     The bodily function monitored by the second sensor can be any parameter such as, for example, a heart rate, a pulse rate, a blood oxygen level, or an amount of exuded sweat. The second metric can be indicated in various forms in accordance with the type of bodily function monitored. For example, the second metric can be a numerical value that quantifies a heart rate (beat per minute), a blood pressure parameter (diastolic and systolic values), or a percentage value (95 percent blood oxygen level). The second sensor can produce the second metric continuously, repetitively, or intermittently at various instants in time. In one application, the second metric may be produced after the individual has completed performing physical exertion activity (blood oxygen level at termination of the physical exertion activity). In another application, the second metric may be produced in real time as the individual is performing the physical exertion activity, such as, for example, a heart rate when the physical exertion activity is being carried out. The individual may have a low heart rate at a first instant in time when beginning the physical exertion activity. At a later instant in time, the individual may have a higher heart rate during peak physical exertion. In yet another application, the second metric may be generated by a sweat sensor and provides an indication as to an amount of sweat exuded by the individual when performing the physical exertion activity. 
     The user device includes elements such as, for example, a memory and a processor. The memory constitutes a non-transitory computer-readable medium that is used to store computer-executable instructions. The processor is configured to access the memory and execute the computer-executable instructions to perform various actions. In one application, the user device is configured to receive the first metric from the first sensor and the second metric from the second sensor. The first metric and/or second metric may be received by the user device in various ways such as, for example, via a wireless communication link and/or a wired communication link, and can be provided in various formats such as for example, an analog signal or a digital signal. The analog signal and/or digital signal may be received in an input interface circuit of the user device that may condition the analog signal and/or digital signal for storing in the memory and/or for processing by the processor. 
     The processor may operate upon the first metric and the second metric by first evaluating the second metric to verify that the first metric represents movement activity being performed by the individual and not by an object such as the dog or the washing machine described above. 
     The verification may be carried out in various ways. In one case, the processor may correlate the second metric to the first metric based on the nature of the bodily function monitored by the second sensor. When the bodily function is a heart rate, for example, the processor can compare the heart rate indicated by the second metric to a nominal reference value. The normal reference value may be based, for example, on a survey, a study, existing medical records, etc. that provides heart rate values for various age groups at various exercise levels. Such parameters are often displayed on exercise equipment in a gymnasium (on a treadmill, for example). A similar approach can be taken for bodily functions such as pulse rate, blood oxygen level, an amount of exuded sweat, etc. 
     In another case, the processor may correlate the second metric to the first metric by verifying that a separation distance between the first sensor and the user device is within a threshold separation distance. This procedure may identify situations such as where an individual is attempting to cheat by attaching the first sensor to a dog or a washing machine and the second sensor is located in the user device which is a smartphone carried by the individual. In one example scenario, the second sensor may be located in a wearable device (a Fitbit®, for example) that is communicatively coupled to the user device via a wireless communication medium (wi-fi, near field communication (NFC), etc.). The threshold separation distance in this scenario may be set on the basis of one or more characteristics of the wireless communication medium such as, for example, a wireless signal range of a signal transmitted by the wearable device. The wireless signal strength in the user device may be weak or non-existent when the wearable device is attached to the dog, for example. The processor may then conclude that the individual is attempting to cheat. In another case, the threshold separation distance may be set to any desired value, such as 6 feet, for example. 
     After the verification indicates that the first metric is indeed originated by the individual (and not by a dog or washing machine, for example), the processor executes a cryptocurrency generation procedure independently, or in cooperation with another compute. When executed independently, the user device (smartphone, a laptop computer etc.) can be operated offline, thereby ensuring that the individual has privacy. Privacy can be important for various reasons. For example, the individual may desire to maintain his/her cryptocurrency activities and/or information (folder location, balance value, etc.) confidential. When executed in cooperation with another computer or computers, the user device may harness the computing capability of the other computer(s), thereby allowing optimizing of hardware and software in the user device to meet various goals such as, for example, cost, reduced electricity consumption, battery power conservation, simpler software, and fewer specialized components (complex number crunching processors, for example). 
     The processor may evaluate the first metric and/or physical exertion activity to determine if a health improvement target of the individual has been satisfied. In one example scenario, the result of the evaluation may be provided in binary form such as a pass or fail grade. The processor awards the cryptocurrency to the individual when the individual obtains a pass result and vice-versa. In another example scenario, the result of the evaluation may be provided in the form of a performance improvement on the part of the individual when striving to meet a desired target threshold (number of pushups, for example). The value of the cryptocurrency awarded by the processor in this scenario may be proportional to the level of achievement by the individual. 
     Additional steps performed by the processor in the user device may include, for example, converting a cryptocurrency award from one format to another (from Bitcoin to Ethereum, for example), converting various types of cryptocurrency awards to a standardized form (number of award points, number of credits, etc.), and/or communicating with other computers for various reasons. For example, the processor in the user device may communicate via the network  75  with the blockchain server  300  to transmit the cryptocurrency to another entity and/or to participate in cryptocurrency generation activities with others. As another example, the processor in the user device may communicate via the network  75 , with a computer system of a credit bureau to update a credit history of the individual and/or to fetch a credit score of the individual prior to, during, or after, the physical exertion activity performed by the individual is evaluated for determining the cryptocurrency award. In one application in accordance with invention, the block chain server  300  is operated by a credit bureau and the processor in the user device may communicate via the network  75  with the block chain server  300 , thereby allowing for integration of credit-related data/information into the cryptocurrency generation process performed by the processor in the user device. At least some traditional cryptocurrency generation systems that use blockchain processes may exclude/preclude credit bureau participation, thereby allowing cryptocurrency generation to be performed by criminal entities in at least some cases. 
     In another embodiment in accordance with the invention, a method for rewarding and/or penalizing an individual is based on assessing a movement activity performed by the individual. The method may include various actions such as, for example, receiving by a user device, from a server computer, a health improvement target assigned to the individual. The movement activity may be associated with physical exertion activity performed by the individual in a gymnasium, for example. The amount of kinetic energy generated by the individual as a result of the movement activity is determined. The user device may then determine whether the individual has satisfied the health improvement target, based on evaluating the movement activity of the individual and/or the amount of kinetic energy generated by the individual. The method may further include executing at least a portion of a cryptocurrency generation procedure that awards a cryptocurrency to the individual, subject to the individual satisfying the health improvement target. The cryptocurrency may be generated independently by the user device and/or in cooperation with one or more computers.

     The methods including algorithms described according to the invention may be included directly in hardware or software programs, software applications executed by a processor, or in any combination. Software may reside in the RAM, a flash memory or a read-only memory (ROM), in a programmable memory (PROM) or in an EPROM, EEPROM, registers, hard disks, removable disks, compact disks or other form of storage medium known in the present state of the art. A storage medium, i.e., database, is combined with a processor so that the processor can read the information and write onto the storage medium. Alternatively, the storage medium may reside in a specific integrated circuit (ASIC). The ASIC may reside in a device, a computer, an operating terminal or a mobile device. Alternatively, the processor and the storage medium may reside as electronic components with a single circuit in a device, a computer, an operating terminal or a mobile device. 
     It will also be understood that the one or more computer-executable program code portions may be stored in a transitory or non-transitory computer-readable medium (e.g., a memory, and the like) that can direct a computer and/or other programmable data processing apparatus to function in a particular manner, such that the computer-executable program code portions stored in the computer-readable medium produce an article of manufacture, including instruction mechanisms which implement the steps and/or functions specified in the flowchart(s) and/or block diagram block(s). 
     The one or more computer-executable program code portions may also be loaded onto a computer and/or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer and/or other programmable apparatus. In some embodiments, this produces a computer-implemented process such that the one or more computer-executable program code portions which execute on the computer and/or other programmable apparatus provide operational steps to implement the steps specified in the flowchart(s) and/or the functions specified in the block diagram block(s).
