     FIELD OF USE 
     The present disclosure relates generally to the field of encryption, and more specifically, to methods and systems for location and geolocation-based encryption schemes for securely distributing and accessing messages and files. 
     BACKGROUND 
     Encryption is the process of encoding digital content stored on computer systems, such as messages, data, and/or information in order to protect the confidentiality of the content and to secure such content from unauthorized use. For example, a message may be encrypted into ciphertext using one or more cryptographic techniques. The content may then be read to authorized users only when the content is decrypted. Thus, the primary benefits of encryption is to maintain the data&#39;s integrity and limit access to the data to only authorized users. 
     Despite the various cryptographic techniques available, these techniques do not always provide adequate security. For example, various cryptographic products and software utilize long key lengths. Although longer decryption keys are more powerful, these keys are not a panacea, as the decryption key or password may be compromised through cracking techniques such as the brute force method. Although the brute force method generally requires vast amounts of computing power, and more is needed as the length of the key increase—(e.g., a 32-bit key takes 2̂32 (4294967296) steps while a system with 40 bit keys (e.g., US-exportable version of RC4) generally takes 2̂40 steps), such computing power is generally available at most universities and small companies. 
     Another example is the use of identity-based encryption schemes. Identity-based encryption allows a party to create a public key based upon a public, unique identifier such as an e-mail address. When the sender desires to send an encrypted message to a recipient, the sender would only need to know the identifier for sending the message. Once receiving the encrypted message for the first time, the recipient would then request the corresponding private key from a trusted third party (i.e., Private Key Generator (PKG)). The private key is then preferably used to decrypt the message. 
     Unfortunately, once the third party PKG is compromised, all messages protected over the entire lifetime of the public-private key pair used by that particular server may also be compromised. Thus, the third party PKG generally becomes a prime target to adversaries or to those seeking to break the encryption(s). Although a master private-public key pair may be updated with a new independent key pair, this may create a key-management problem, as most users must have the most recent public key for the server. 
     Accordingly, there is a need for a new and improved method for encrypting messages and digital data content. Preferably, the new and improved encryption method utilizes geolocation data and internet protocol address data to improve security. 
     SUMMARY OF EMBODIMENTS

     It is an object to provide a method that encrypts digital content stored on a user&#39;s device. Preferably, the encryption method utilizes a key based on various geolocation data such as global positioning system (GPS) data generated by the mobile computing device and gyroscope data. The key of the encryption method may also utilize a device identification data such as an internet protocol (IP) address and machine access control (MAC) address of the mobile computing device to encrypt and decrypt the digital content. The key of the encryption method may also utilize a unique file identifier associated with the digital content to be encrypted. 
     It is an object to provide a method that enables communication privacy between various individuals. Preferably, the method enables a user to publish a public comment regarding any location in the world and on the nature, activity, substance and condition of that location by “dropping” messages tied to that location. 
     It is an object to provide a method that encrypts digital content stored on a user&#39;s device with a key utilizing: (1) geolocation data (e.g., GPS coordinates data, gyroscope data) and (2) device identification data (e.g., IP address data, MAC address data). The geolocation data may be provided by the user via the following steps: (i) loading a digital map using the encryption application running on the mobile computing device of the user; (ii) selecting a target location on the digital map (e.g., dropping a pin of the target location on the digital map) to obtain GPS coordinates; and (iii) using the GPS coordinates as the geolocation data for the key. 
     In order for the recipient to decrypt the digital content, the recipient may decrypt such content via multiple approaches. In one embodiment, the recipient may decrypt the encrypted content by performing the following steps: (i) visiting the target location selected by the user, such that the GPS coordinates generated by the recipient&#39;s mobile computing device fulfill the geolocation data portion of the key; (ii) activating the camera function on the mobile computing device; and (iii) viewing the decrypted digital content on the display screen of the mobile computing device. The IP address and MAC address of the recipient&#39;s mobile computing device may be used to satisfy the device identification data portion of the key. Additionally, the gyroscope data generated by the mobile computing device may be used to orient the device at a particular angle for viewing the decrypted message. Thus, in this embodiment, the recipient preferably decrypts the encrypted digital content by physically visiting the target location selected by the user. 
     In another embodiment, the recipient may decrypt the encrypted content by performing the following steps: (i) loading a digital map using the encryption application running on the recipient&#39;s mobile computing device; (ii) inputting or selecting the target location selected by the user previously (e.g., dropping a pin of the target location on the digital map); and (iii) based on the target location inputted by the recipient, using the GPS coordinates of that target location to satisfy the geolocation data portion of the key. The IP address and MAC address of the recipient&#39;s mobile computing device may be used to satisfy the device identification data portion of the key. Thus, in this embodiment, the recipient may decrypt the encrypted digital content simply by selecting the target location on a digital map without having to physically visit the target location. 
     In another embodiment, the geolocation-based encryption method may be used to create a scavenger hunt. In one embodiment, the scavenger hunt may allow a user to create a series of clues which are accessible by a scavenger hunt participant once one or more of the decryption key parameters are met or substantially met. The clue may be displayed as an overlay, as described above, or by another way of communicating information to the scavenger hunt participant. The clue may provide the scavenger hunt participant with a hint as to how to meet one or more of the decryption key parameters of the next clue in order to view the next clue. The scavenger hunt may have a series of clues, with each clue directing the scavenger hunt participant to find a next clue until the scavenger hunt has been completed. 
     In another embodiment, the scavenger hunt may allow the recipient to decrypt messages that direct one or more recipients to visit additional target locations in order to obtain additional clues for the scavenger hunt. Specifically, when a recipient decrypts the encrypted content by physically visiting the target location, the decrypted digital content may include additional clues for the next target location. 
     In another embodiment, the method may include advertisements. Specifically, in this embodiment, when the recipient decrypts the encrypted content, the decrypted digital content may comprise advertisements that promote the goods or services for a company. 
     In various embodiments, the server may store the following: (1) the encrypted digital content, (2) unique file identifier associated with that digital content; and (3) IP address or mobile computing device of the user or intended recipient. The user or recipient may then download or retrieve that encrypted digital content if the IP address of the user&#39;s or recipient&#39;s mobile device is verified by the encryption application running on that mobile device. This may be achieved by cross checking the IP address of the user&#39;s or recipient&#39;s mobile device and the IP address stored in the server. Once verified, the user or recipient may download or retrieve the encrypted digital content. 
     In another embodiment, after the encrypted digital content is downloaded to the user&#39;s or recipient&#39;s mobile computing device, the user&#39;s or recipient&#39;s mobile computing device may also store the following: (1) unique file identifier associated with that digital content and (2) geolocation data. The user or recipient may then proceed in having the encryption application decrypt the encrypted digital content. In doing so, the encryption application may verify the geolocation data stored in the mobile computing device by checking the (1) unique file identifier associated with that digital content and/or (2) geolocation data. Once verified, the encryption application may proceed with the decryption of the encrypted digital content. 
     It is an object to provide a computer-based method that allows users to view decrypted digital content via a camera and a display screen of the mobile computing device. 
     It is an object to provide a new method for promoting advertisements via geolocation-based encryption. Preferably, users utilizing the cameras on their mobile phones may be able to decrypt and view messages that have been created for the general public to view. Preferably, these public messages are viewable only at the locations where they were originally created. 
     It is an object to overcome the deficiencies of the prior art.

     Definitions 
     In the following description, certain terminology is used to describe certain features of one or more embodiments. For instance, the terms “computer”, “computer system”, and “mobile computing device” generally refer to any apparatus or device that processes information with an integrated circuit chip, including without limitation, mainframe computers, workstations, gaming consoles, servers, desktop computers, portable computers, laptop computers, and embedded computers. Furthermore, the term “mobile computing device” may refer to any wireless electronic devices including smart phones, cellular phones, tablet computers, personal digital assistants, digital media players, portable game players, and hand-held computers. 
     As used herein, the terms “Internet” or “Cloud” generally refers to any collection of networks that utilizes standard protocols, whether Ethernet, Token ring, Wi-Fi, asynchronous transfer mode (ATM), Fiber Distributed Data Interface (FDDI), code division multiple access (CDMA), global systems for mobile communications (GSM), long term evolution (LTE), or any combination thereof. 
     As used herein, the terms “application”, “software”, “encryption application”, or “software application” generally refer to any set of machine-readable instructions on a client machine, web interface, mobile computing device, and/or mobile computing device, that directs a processor to perform specific steps, processes, or operations disclosed herein. 
     As used herein, the term “geolocation” generally refers the process or technique of identifying the geographical location of a person or device by means of digital information processed via the Internet. Thus, geolocation-based encryption may refer to technology that utilizes a user&#39;s location when using the Internet or a mobile phone. The term “geolocation data” may refer to data that is utilized for locating a user, including without limitation, network router list data, global positioning satellite data, internet protocol address data, gyroscope data, and an accelerometer data. The term “network router list data” may refer to any data or information pertaining to the existing routers at an actual, physical location of a user. 
     The present specification discloses a geolocation-based encryption method and system. The method and system may be used to encrypt and decrypt digital content based on a location selected by a user. Specifically, a user may encrypt a message and its attachments using a software algorithm that creates a key based on, inter alia, geolocation data (e.g., global positioning satellite (GPS) data, gyroscope data) and/or device identification data (e.g., internet protocol (IP) address data, machine access control (MAC) address data) of the mobile computing device of the user(s) or recipient(s). The recipient may then decrypt the message and attachments based on the key using the same type of data—e.g., GPS, gyroscope, and IP address—of the recipient&#39;s mobile computing device. 
     In particular, when encrypting a message, the GPS capabilities and gyroscope data of the mobile computing device may be used by the encryption software to create a key. Optionally, data pertaining to a list of networking hardware (e.g., network routers) near (or at least within range of) the user and mobile computing device (i.e., network router list data) may also be sent to the encryption software as part of the key. For example, in one embodiment, the list of networking hardware may be acquired by the mobile computing device by scanning and receiving of wireless signals of the networking hardware located near the mobile computing device of the user. After the digital content is encrypted, the digital content may be sent and stored on a server and may be accessible by the recipient only when the recipient inputs the proper target location or is at the target location. Preferably, the message is addressed to a specific device owned by the recipient via a unique identification number (e.g., IP address/MAC address of the mobile computing device). That way, the message may only be decrypted by that specific mobile computing device. 
     In order for the recipient to decrypt the digital content, the recipient may decrypt such content in various approaches. In one embodiment, the recipient may decrypt the encrypted content by performing the following steps: (i) visiting the target location selected by the user, such that the GPS coordinates generated by the recipient&#39;s mobile computing device fulfill the geolocation data portion of the key; (ii) activating the camera function on the mobile computing device; and (iii) viewing the decrypted digital content on the display screen of the mobile computing device. The IP address and MAC address of the recipient&#39;s mobile computing device may be used to satisfy the device identification data portion of the key. Additionally, the gyroscope data generated by the mobile computing device may be used to orient the device at a particular angle for viewing the decrypted message. Thus, in this embodiment, the recipient preferably decrypts the encrypted digital content by physically visiting the target location selected by the user and perhaps orienting the device at a particular angle. 
     In another embodiment, the recipient may decrypt the encrypted content by performing the following steps: (i) loading a digital map using the encryption application running on the recipient&#39;s mobile computing device; (ii) inputting or selecting the target location selected by the user previously (e.g., dropping a pin of the target location on the digital map); and (iii) based on the target location inputted by the recipient, using the GPS coordinates of that target location to satisfy the geolocation data portion of the key. The IP address and MAC address of the recipient&#39;s mobile computing device may be used to satisfy the device identification data portion of the key. Thus, in this embodiment, the recipient may decrypt the encrypted digital content simply by selecting the target location on a digital map without having to physically visit the target location. 
     In another embodiment, the key may comprise network router list data, IP address, GPS coordinates, and gyroscope data, which may then be used to decrypt the message. For instance, by positioning the camera and display of the mobile computing device at the target location and by compiling a list (complete or partial) of networking hardware nearby the mobile electronic device, the user may then decrypt the message and access and view the encrypted and previously hidden message. 
     In the event that the recipient is located somewhat near the desired location, but not at the precise targeted area, the software may direct the intended recipient to the exact location to enable the recipient to decrypt the message. 
     In various embodiments, the geolocation-based encryption method and system may also utilize generic public message by using digital advertising space, which would be visible when users use their electronic device to search for the exact physical location of the message. For example, the public message may be in the form of advertisements. The advertisement may appear to the user via the camera of the mobile computing device. 
       FIG. 1  is an illustration of one embodiment of a geolocation-based encryption method. As shown in  FIG. 1 , one embodiment of the geolocation-based encryption method  100  may comprise steps  105 ,  110 ,  115 ,  118 ,  120 ,  125 ,  130 ,  135 ,  140 . Specifically,  FIG. 1  shows that the method  100  may comprise the first step  105  of providing an encryption application. The encryption application is generally an application or software program that runs on a computer system or mobile computing device and may be configured to encode or encrypt digital content such as a message, image, or video so that the encrypted digital content can be read only by the user/sender and/or intended recipient(s). Importantly, the encryption application may also be configured to encrypt such digital content based on, inter alia, geolocation data. For example, in one embodiment, the encryption application may encrypt digital content based on a key utilizing geolocation data such as GPS data (e.g., GPS coordinates). In another embodiment, the encryption application may also encrypt digital content based on a key utilizing gyroscope data. In various embodiments, the encryption application may also encrypt digital content utilizing other data such device identification data, which may include IP address data and/or MAC address data, and perhaps a unique file identifier associated with the digital content to be encrypted. This will preferably allow only the sender or the intended recipient to receive, decrypt, and/or view the digital content. In various embodiments, the encryption application may also be configured to decode or decrypt the encrypted digital content. 
       FIG. 1  also shows the next step  110 , which may be prompting the user of a first mobile computing device to select a target location. This may allow the encryption application to also create global positioning system data, which may be at least part of the geolocation data necessary for a key. The global positioning system data may, for example, be latitudinal and longitudinal coordinates of a specific location on a map, and, in some embodiments, the latitudinal and longitudinal coordinates may be converted to a numeric or alphanumeric value used for the encryption key. 
     In one embodiment, the user may select a target location by simply touching or pinning a target location shown on that digital map. Specifically, the user may first launch a digital map on his or her mobile computing device via the encryption application and touch or “pin” the exact target location on that digital map. In another embodiment, the user may select a target location by simply inputting the GPS coordinates into the encryption application. In this manner, the user may type the desired GPS coordinates into the encryption application in order to select the target location. In various embodiments, the user may need to be physically present at the target location in order to select a target location. 
     In addition to geolocation data, the encryption application may also utilize the IP address and/or MAC address of the mobile computing device of the user or recipient to further strengthen the encryption of the digital content. The encryption application may also use a unique file identifier associated with the digital content as part of the key to also further strengthen the encryption of the digital content. The unique file identifier may be a unique alphanumeric or numeric value assigned to that particular digital content. 
       FIG. 1  also shows that, in other embodiments, the geolocation-based encryption method  100  may also comprise step  115 , which may be prompting the user to physically orient the first mobile computing device to a target orientation to create a target gyroscope data. This step may be attributed to certain embodiments of the geolocation-based encryption method  100 . As discussed above, the geolocation data may also comprise gyroscope data, which may require that the recipient orient his or her mobile computing device at a particular angle (i.e., target orientation) in order to unlock or decrypt the encrypted digital data. For example, the user may first create a key with gyroscope data, requiring that the recipient orient his or her mobile computing device facing northwest at approximately a 40 degree angle. Thus, in this manner, in addition to being physically at the target location, the recipient may view the hidden or encrypted message only when the recipient orients his or her mobile computing device at that particular angle. 
     Once the geolocation data is inputted by the user or entered into the encryption application, the encryption application may also prompt the user or retrieve other data for the encryption key. Such data may include device identification data (e.g., internet protocol address of the user or recipient of the digital content) and the unique file identifier associated with the digital content. Various embodiments of the encryption application may utilize a single form of data (e.g., geolocation data only) or possibly the geolocation data, device identification data, and unique file identifier data. 
     Once the data or information is obtained by the encryption application, the geolocation-based encryption method may perform the next step  120 , which may be generating a key. As discussed above, in one embodiment, the key may be generated based on a geolocation data, a device identification data, and a unique file identifier associated with the digital content. Preferably, the encryption application preferably encodes digital content based on an encryption key. In one embodiment, the key may comprise portions that pertain to geolocation data such as GPS coordinates (e.g., latitude/longitude coordinates) and/or gyroscope coordinates. For example, the key may include GPS data of the target location of the intended recipient(s). The GPS data of the target location may be a particular location only known to the sender and recipient such as the user&#39;s or recipient&#39;s residence, business address, or special location known only between the user and recipient. In another embodiment, the geolocation data may also comprise gyroscope data that only unlock the encrypted digital data when the mobile computing device is oriented at a particular angle (i.e., target orientation) for viewing the decrypted message. For example, the user, using the encryption software, may create a key requiring geolocation data for the orienting the recipient&#39;s mobile computing device facing north at approximately a 45 degree angle. In this manner, the hidden or encrypted message may unlock and be viewable in the recipient&#39;s mobile computing device only when the recipient&#39;s mobile computing device is likewise positioned at that angle. 
     Additionally, the key may comprise device identification data such as the IP address of recipient and a unique file identifier, which may a specific value assigned to the digital content to be encrypted. For example, in one embodiment, the key may comprise the geolocation data and a unique file identifier. In another embodiment, the key may comprise the geolocation data, a unique file identifier, and an IP address of the recipient. 
     Once the key has been created, the encryption application may perform step  125 , which may be encrypting the digital content stored in a computer readable storage medium based on the key. As discussed above, the digital content may be encrypted by the encryption application and may include, without limitation, a message, image, advertisement, direction, file, or any other piece of digital information. In one embodiment, the digital content may be created by the user or may be uploaded to a computer readable medium of the mobile computing device. In an alternative embodiment, the user may also download the digital content from the Internet or networked computers. The user may also, in another embodiment, create the digital content via a message and “drop” that message to a particular location on a map, such that the message is tied to that location. Preferably, the digital content to be encrypted is stored in a computer readable storage medium of the device running the encryption application. 
     The digital content may then be encrypted via one or more encryption algorithms that utilize various parameters including location, orientation, device identification, and/or a unique file identifier. The location parameter may be based on GPS coordinate data such as the latitude and longitude generated by the mobile computing device. Alternatively, the GPS coordinate data may simply be inputted by the user. In one embodiment, the location may be provided by inputting geographic locations, such as selecting a target location on a digital map displayed on the mobile computing device. 
     Regarding the orientation parameter, a gyroscope component of the mobile computing device may be used to provide the gyroscope data for orienting the device at a certain approximate angle. The gyroscope data may be inputted by the user or may be recorded by the encryption application when the mobile computing device is positioned at a certain angle. 
     Regarding the device identification parameter, this parameter may comprise the IP address or MAC address of the mobile computing device and may be inputted by the user. In one embodiment, the user may select the recipient of the digital content, and in doing so, the encryption application may retrieve the recipient&#39;s IP address of his or her device. In another embodiment, the user may select the recipient of the digital content, and the encryption application may retrieve both the recipient&#39;s IP address and MAC address. The encryption application may then use the IP address and/or MAC address as part of the key. 
     After the digital content is encrypted in step  125 , the encryption application may perform step  130 , which may be establishing one or more secure sessions among the user, a recipient of the digital content, and/or the one or more servers. Here, various security protocols may be used to establish a secure session to allow the transmission of sensitive data across the different communication networks. This will preferably allow the encrypted digital data to remain secure and un-tampered from unauthorized recipients. In one embodiment, the user&#39;s mobile computing device may require a negotiation or handshaking phase that requires the server to verify that the intended sender is the authorized user. For example, the user or client may exchange a handshake with a server to establish a secure session. In response, the server may transmit various security operations, which may a primitive security operation or a macro security operation. The mobile computing device of the user, for instance, may initially transmit various messages or utilize a random number generator to generate and store a random number(s) in response to s random number operation. In another embodiment, random numbers may be generated in advance of establishing the session, which may generate a hash of the accumulated handshake messages. The server may then transmit a message or certificate for authorized access. In another embodiment, the encryption application and server may not utilize security questions, random number generators, messages, or certificates. 
     Once the secured sessions are established, the encrypted digital content may be transmitted to the second mobile computing device via one or more servers, as shown in step  135 . In one embodiment, the encrypted digital content may first be transmitted to a server or database for storage and then retransmitted to the recipient&#39;s second mobile computing device for decrypting. Specifically, the recipient may download or access the encrypted digital content, and the encrypted digital content may first be verified by cross-checking the IP address and/or MAC address of the mobile computing device of the intended recipient. This may be accomplished by having the IP address or MAC address verified by checking the key created by the encryption application. Thus, once the encrypted digital content is downloaded to the second mobile computing device, the user may then decrypt the digital content using the encryption application. 
     In another embodiment, the encrypted digital content may first be transmitted to a storage medium in a server and then decrypted before being transmitted to the second mobile computing device. Specifically, the recipient may first access and decrypt the encrypted digital content while that encrypted digital content is stored in the server. Once decrypted, the recipient may then download or access the decrypted digital content using the second mobile computing device, and the decrypted digital content may be verified by cross-checking the IP address and/or MAC address of the mobile computing device of the intended recipient. Both the IP address and MAC address may be verified by checking the key created by the encryption application. Preferably, the encrypted digital content is stored in the database or server, so that the intended recipient may access such digital content via the Internet or network. 
     Still, in an alternative embodiment, the encrypted digital content may be stored in the user&#39;s first mobile computing device and not be transmitted to a server for storage. Here, in this embodiment, the digital content may be encrypted using only the geolocation data and the unique file identifier associated with that digital content without the device identification data (e.g., IP address). Thus, when the decrypting the encrypted digital content, the encryption application may check the unique file identifier, and the user may then decrypt the digital content by simply inputting the correct geolocation data or GPS coordinates into the encryption application. 
       FIG. 1  also shows that the geolocation-based encryption method  100  may also comprise step  135 , which may be downloading the encrypted digital content from the server(s). This downloading may be based on various data stored along with the encrypted digital content such as device identification data (e.g., IP address) and/or the unique file identifier that is associated with the encrypted digital content. Here, in one embodiment, the encrypted digital content may be stored in a server along with other forms of data such as the unique file identifier data and the IP address of the recipient&#39;s mobile computing device. The recipient or user requesting to download the digital content may make a request to the server via the encryption application. Before downloading the encrypted digital content from the server(s), the encryption application may first verify the device identification data of the recipient (e.g., IP address) and/or the unique file identifier. Once verified, the encrypted digital content may be downloaded to the recipient&#39;s device. 
       FIG. 1  also shows step  140  of the geolocation method  100 , which may be decrypting the encrypted digital content based on the key to create the decrypted digital content. In various embodiments, the decryption of the encrypted digital content may utilize various parameters similar to the encryption algorithm parameters. For example, in one embodiment, in order to decrypt the digital content, the recipient may be required to have the same location, orientation, and identification parameters as utilized by the encryption algorithm. For example, in one embodiment, the intended recipient may utilize the encryption application to access the digital content. In doing so, the user may encrypt the digital content with a key comprising a geolocation data, which may include the target location selected by the user (and known only between the user and intended recipient). The intended recipient may then decrypt the encrypted digital data by simply selecting the target location. In this manner, the recipient may access the digital content without having to physically be at the target location. For example, the recipient may decrypt the encrypted content by performing the following steps: (i) loading a digital map using the encryption application running on the recipient&#39;s mobile computing device; (ii) inputting or selecting the target location selected by the user previously (e.g., dropping a pin of the target location on the digital map); and (iii) based on the target location inputted by the recipient, using the GPS coordinates of that target location to satisfy the geolocation data portion of the key. The IP address and/or MAC address of the recipient&#39;s mobile computing device may also be used to satisfy the device identification data portion of the key. The unique file identifier may also be used to satisfy a portion of the key. Thus, in this embodiment, the recipient may decrypt the encrypted digital content simply by selecting the target location on a digital map without having to physically visit the target location. 
     In another embodiment, step  135  may be performed by requiring the intended recipient to be physically located at the targeted location. Specifically, in this embodiment, the user may encrypt the digital content by selecting a target location known only known between the user and intended recipient. The intended recipient may then decrypt the encrypted digital data by visiting the target location with his or her mobile computing device. In this manner, the digital content such as a message may be securely accessed by intended recipient only if the recipient is at the target location. For example, the recipient may decrypt the encrypted content by performing the following steps: (i) visiting the target location selected by the user, such that the GPS coordinates generated by the recipient&#39;s mobile computing device fulfill the geolocation data portion of the key; (ii) activating the camera function on the mobile computing device; and (iii) viewing the decrypted digital content tied to that location on the display screen of the mobile computing device. The IP address and MAC address of the recipient&#39;s mobile computing device may be used to satisfy the device identification data portion of the key. Additionally, the gyroscope data generated by the mobile computing device may be used to orient the device at a particular angle for viewing the decrypted message. The unique file identifier may also be used to satisfy a portion of the key. Thus, in this embodiment, the recipient preferably decrypts the encrypted digital content by physically visiting the target location selected by the user. 
     In various embodiments, one or more image overlays may be generated when the recipient visits the targeted location. These image overlays may vary based on how closely the key parameters match the parameters used by the encryption algorithm. For example, if the actual location of the recipient&#39;s mobile computing device and the parameters set by the encryption algorithm have a difference of several feet, the overlay may signal recipient where to move in order for the location of the mobile computing device to match the parameters of the encryption algorithm. In other embodiments, the image overlay may also comprise messages, advertisements, information, data, directions, or anything else that may be displayed on the display. 
     In various embodiments, the mobile computing device of the user or recipient may also store the following: (1) unique file identifier associated with that digital content and (2) geolocation data. The user or recipient may then proceed in having the encryption application decrypt the encrypted digital content. In doing so, the encryption application may verify the geolocation data stored in the mobile computing device by checking the (1) unique file identifier associated with that digital content and/or (2) geolocation data. Once verified, the encryption application may proceed with the decryption of the encrypted digital content. 
       FIG. 2  is a block diagram of one embodiment of a mobile computing device.

The disk controller  225  may be configured to control the computer-readable medium  205 , which may be a hard drive and/or optical disk drive. The computer-readable medium  205  may also be another form of random access memory or flash memory. The display controller  225  may be coupled to a display  210  such as a liquid crystal display (LCD), projection system, or touchscreen. The I/O interface  240  may be coupled to one or more input devices such as an interface device  255  (e.g., mouse, keyboard, pointing device, touchscreen) or camera  250 . The camera  250  may be any component or electronic device capable of viewing an environment and/or capturing one or more images and/or videos onto an electronic memory component. In additional embodiments, the mobile computing device  200  may also comprise a network controller card that may connect to a network, such as the Internet or along an Intranet. In various embodiments, the mobile computing device  200  may include mobile computing devices, including without limitation, laptops, smartphones, tablets, and wearables. 
     The processor  245  may be configured to execute a set of computer readable instructions and further to execute a software program, application or computer implemented instructions described herein such as the customer feedback application. The computer readable instructions and application may comprise instructions that cause the processor  245  to perform one or more processes when the instructions are executed by the processor  245 . In other various embodiments, the computer readable instructions or application may be tangibly embodied in the memory of the mobile computing device  200  such as the RAM  235  or ROM  215 , as shown in  FIG. 2 , or on a computer-readable storage medium, such as a magnetic, optical or solid-state digital storage medium. 
     The GPS receiver  260  preferably collects GPS signals and data from GPS satellites. The gyroscope component  265  preferably gathers orientation data of the mobile computing device. Although  FIG. 2  shows that the computing device  200  comprises thirteen components, it should be understood that the computing device may comprise any number of components. 
       FIG. 3  is an illustration of one embodiment of the geolocation-based encryption system. As shown in  FIG. 3 , one embodiment of the geolocation-based encryption system  300  may comprise: one or more mobile computing devices,  301 ,  302 ,  303 ,  304 , and one or more servers, which are preferably part of the Cloud or Internet  310 . Here, one embodiment of the geolocation-based encryption system  300  may utilize GPS satellites for generating the GPS signals for the geolocation data portion of the key disclosed herein. The key may be based on latitude, longitude, and altitude generated by GPS satellites  315 ,  320 , but may also comprise other parameters such as gyroscope orientation of the mobile computing device, as determined by a gyroscope component. Furthermore, the key may also require specific information, which may be unique, inherent, or generated by the mobile computing device, such as an IP address or MAC address. 
       FIG. 4  is a screenshot of one embodiment of the encryption application and shows how a user may select a target location on the encryption application. As shown in  FIG. 4 , one embodiment of the encryption application  400  may comprise: a pin  405  and a digital map  410 . As discussed above, a user may select a target location on the encryption application  400  by first loading a digital map  410 , and selecting the target location  415 . The target location  415  may be selected by inputting a pin  405  on the digital map  410  of the user&#39;s mobile computing device. This may allow the user to create the geolocation data portion of the key and may allow the user to drop a digital content (e.g., message) at a particular location. Similarly, in other embodiments, the recipient may select the target location by simply inputting a pin on a digital map on the recipient&#39;s mobile computing device. 
       FIG. 5  is an illustration of one embodiment of the mobile computing device and shows how a recipient can decrypt an encrypted digital content by orienting the mobile computing device. As shown in  FIG. 5 , one embodiment of the mobile computing device  500  may comprise an encrypted application  505  with a display  510 .  FIG. 5  shows that, upon arriving at the target location, the recipient may utilize the camera of the mobile computing device  500  to create an image or live video feed of the environment using the display  510 . Based on the: (1) GPS data of the recipient&#39;s mobile computing device  500 , as determined by the GPS satellite data feed; (2) orientation of the recipient&#39;s mobile computing device  500  as determined by gyroscope component; and (3) device identification information as determined by the IP address and/or MAC address, the digital content  515 ,  516 , which may be one or more messages tied to that target location, may be shown on the display  510  via an image overlay. Preferably, the digital content  515 ,  516 , is superimposed over the environment when displayed with the environment and may only be accessible near the target location of the recipient. In another embodiment, the digital content  515 ,  516 , may also be available only when the recipient views messages through the camera of his or her mobile computing device when positioning the mobile computing device at a certain orientation/angle. Thus, once the mobile computing device  500  has met the requirements for the key such as geolocation data (e.g., GPS coordinates, gyroscope data) and device identification data (e.g., IP address, MAC address), then the digital content may be decrypted. 
       FIG. 5  shows that, in one embodiment, the camera of the mobile computing device  500  may generate an image of the decrypted digital content, which may be visible on the display, over the environment. The decrypted digital content may include, without limitation, messages, pictures, images, advertisements, directions, or other forms of communication. 
       FIG. 6  is an illustration of another embodiment of the mobile computing device and shows how a recipient can decrypt an encrypted digital content by orienting the mobile computing device. As shown in  FIG. 6 , another embodiment of the mobile computing device  600  may comprise an encrypted application  605  with a display  610 . Like the previous embodiment, shown in  FIG. 5 , another embodiment of the mobile computing device  600  may allow a recipient or user to view the decrypted digital content  615 ,  616 ,  617 ,  621  tied to the target location through his or her mobile computing device  600  when positioning the mobile computing device  600  at a target location (e.g., mall) and at a certain orientation. The decrypted digital content  615 ,  616 ,  617 ,  621  may include messages or advertisements from other users who had visited the target location and desired to leave a location specific message. For example, as shown in  FIG. 6 , the decrypted digital content  615 ,  616 ,  617 ,  621  may be an advertisement posted by a store located at the target location, wishing to inform recipients of a sale, but only if the recipient is at the desired location. The decrypted digital content  615 ,  616 ,  617 ,  621  may also be visible only when the user is at the target location and has his or her mobile computing device  600  oriented in a particular manner. 
       FIG. 7  is an illustration of another embodiment of the mobile computing device and shows how a recipient can decrypt an encrypted digital content by orienting the mobile computing device with a display. As shown in  FIG. 7 , another embodiment of the mobile computing device  700  may comprise an encrypted application  705  with a display  710 .  FIG. 7  shows that the decrypted digital content  715  may be a message requesting information from a recipient. For example, in one embodiment, a user may create a message, which becomes encrypted by the geolocation-based encryption method  100  and tied to the target location. The message is preferably not displayed unless the recipient arrives at the target location and orients his or her mobile computing device  700  at a specific angle or orientation. Once the recipient arrives at the target location and orients the mobile computing device  700  at the desired orientation, the encrypted digital content may decrypted and may be accessed by the recipient. 
       FIG. 8  is an illustration of another embodiment of the mobile computing device and shows how a recipient can decrypt an encrypted digital content by orienting the mobile computing device with a display while using a filter. As shown in  FIG. 8 , another embodiment of the mobile computing device  800  may comprise an encrypted application  805  with a display  810 .  FIG. 8  shows that, in one embodiment, the user may add digital content to a large environment such as a cityscape and tie that digital content to that location. In that environment, the user may then add various encrypted digital content, which may be visible on the display  810  of the mobile computing device  800 , depending on the location and orientation of the mobile computing device  800 . Because it may be possible that the decrypted digital content  815  may comprises multiple messages, the user may apply a filter  820 , which may limit unwanted messages visible to the recipient and display  810 . For example, in one embodiment, the filter  820  may only allow restaurant messages to be displayed, thereby only allowing restaurant-related messages to be visible on the display  815 . Additionally, because the recipient is at the desired location that substantially matches the decryption key parameters, the decrypted digital content  815  may have an indicator to direct and guide the recipient to the specific location position the mobile computing device  800  at a certain orientation. For example, in the event that the decrypted digital content  815  is not visible, the encryption application  805  may guide the recipient at the desired location to satisfy the geolocation requirements portion for the key. This may be embodied by arrows or directions to guide the user to move and/or position the mobile computing device  800 . 
       FIG. 9  is a screenshot of one embodiment of the encryption application showing a scavenger hunt. As shown in  FIG. 9 , one embodiment of the encryption application  900  may comprise: scavenger hunt locations  905  and a digital map  910 . As discussed above, another embodiment of the geolocation-based encryption method may be used to create a scavenger hunt. The scavenger hunt may allow a user to create a series of clues, which are accessible by one or more scavenger hunt participants. Specifically, once the decryption key parameter(s) are met or substantially met, the scavenger hunt participants may find clues to obtain rewards or prizes (e.g., cash prizes). For example, in one embodiment shown in  FIG. 9 , the digital map  910  may include scavenger locations  905  used for providing clues for rewarding the user or participants with awards and prizes. The scavenger locations  905  may be represented by an image, symbol, or icon such as a strawberry, shown in  FIG. 9 , or any other images, symbols, icons, or text. 
     When participating in a scavenger hunt, the user select one or more scavenger locations  905  loaded on the encryption application  900  on his or her mobile computing device. For example, the user may first load a digital map  910 , and the digital map  910  may populate the scavenger hunt locations  905  on the digital map  910 . After the scavenger hunt locations  905  are populated or shown, the user may select a scavenger hunt location  905  by simply touching or pinning the scavenger hunt location  905  on the digital map. Once the scavenger hunt location(s)  905  are selected, the user may get redirected to a third party&#39;s website such as a sponsor or advertiser. In that website, one or more clues of the scavenger hunt may be provided to the user. Based on the clue(s), the user may then utilize the encryption application  900  to search for the possible locations where the reward or prize is located. For example, in one embodiment, the clue may be displayed as an overlay, as described above, or by another way of communicating information to the scavenger hunt participant. The clue may provide the scavenger hunt participant with a hint as to how to meet one or more of the decryption key parameters of the clue in order to view the next clue. Alternatively, scavenger hunt may have a series of clues, with each clue directing the scavenger hunt participant to find a next clue until the scavenger hunt has been completed. 
     In another embodiment, the scavenger hunt may allow the scavenger hunt participants to decrypt messages that directs them to visit additional scavenger hunt locations  905  in order to obtain additional clues for the scavenger hunt. Specifically, when a scavenger hunt participant decrypts the encrypted content by physically visiting the target location, the decrypted digital content may include additional clues for the next target location.
