Description:
TECHNICAL FIELD 
     The present invention is in accordance with creating electronic contracts, its methods, especially, the sharing of contracts in real time with affiliated partners of the shared terminal by using the set synchronization code. Also, providing precautions and mandatory information input for the contract and also inputting additional information in regards to verifications when the contract is done via a communications network. 
     BACKGROUND OF THE INVENTION 
     Electronic signatures, electronic certifications, and the language used in the certification are a product of neologism and have been developed much to advancements in the internet. 
     The above terminology is affiliated with the person involved verifying that he or she is the actual person via certification, and accurately portrays the contract relations that are due to actions of financial and non financial activities off and online. Also, this involves methods of inputting electronic contracts and in relations to creating proof for future legal issues that may arise. 
     As in the past, the method was as follows, one side of the party agrees with the other involved party and inputs the electronic contract, and inputs an electronic signature, after that, he or she sends an email and the recipient checks the electronic contract, inputs an electronic signature and sends it to a notary. 
     In detail, involved parties and notary receive a certificate from certified institutions such as, the Korean information certificate authority, Korea financial telecommunications and clearings institute, Koscom, etc. After that, one of the party members in agreement with the parties involved inputs an electronic contract and signature and emails this to the other party. Upon receiving the email, the recipient scrutinizes the email and after careful scrutiny, evaluates if the email was sent by the correct party, after, the input of the electronic signature evaluates once more if it is the correct party. 
     If there are no visible issues with the electronic contract &amp; signature, the involved party inputs the electronic signature and sends this to the notary via email. 
     When the notary receives the email from the involved party and carefully scrutinizes over it, and evaluates that there are no problems, he or she inputs an electronic signature into the electronic contract and sends it to the involved parties. 
     However, the above mentioned method is sophisticated and has many complications, such as, due to the parties involved having little or no information as to what they have to input into the electronic contract, he or she may have to make phone calls to make queries or check the internet for possible answers. 
     This calls for various solutions to quicker and easier solutions involving electronic contracts.

     SPECIFIC DETAILS FOR APPLICATION OF INVENTION 
     In accordance to our exercised record,  FIG. 1  or  7  describes equipment and methods for input of electronic contracts via a communications network system. 
     Describes in detail the functions and applications of the invention for ease of comprehension. 
     Also, in explaining the inventions aspects, we can give different reference symbols, and, even though they are different figures, we can give it the same reference symbol. 
     However, despite the situation, the components, in accordance to our exercised record, defines that they have different functions, OR in accordance to different exercised records, can have the same functions. The functions in each component have to be evaluated on the basis of each exercised record of each component. 
     Also, in explaining the components of the invention, terminology of number 1, 2, A, B, (a), (b) can be used. 
     The terminology is there to differentiate between different components, and does not limit or change the nature and order of the related component. 
     Some components may state, ‘connect’, ‘link’, or ‘unify.’ This may actually mean directly connecting the components, however, there may be a medium that ‘connects’, ‘links’, or ‘unifies’ the components. 
     Especially, the involved parties share the information by synchronizing the terminals through the synchronization codes, and also, provide information on precautions and mandatory input information and propose new methods to input set verification information upon receiving verification information after the completion of the electronic contract. 
     In accordance to our exercised record,  FIG. 1  is a figure that shows the system for the input of the electronic contract. 
     As shown in  FIG. 1 , the invention&#39;s electronic contract input system is formed of system user terminal ( 100 ), service server ( 200 ), database ( 300 ), and collaborated server ( 400 ). 
     The user terminal ( 100 ) is linked in with the service server ( 200 ) for input of electronic contract between parties. The user terminal downloads the application through the service server ( 200 ), and applies it for electronic contract input. 
     At this point, for example, the user terminal ( 100 ) can cover cell phones, smart phones, laptops, digital broadcasting equipment, PDA&#39;s, PMP&#39;s, cameras, navigation systems; tablet PCs, e-books, etc. 
     The user terminal ( 100 ) can be classified as a means of electronic contract input shared between at least a number 1 and number 2 users. 
     In other words, we can state that a user possessing a terminal (user 1) shares electronic contract information with a (number 2)  120  terminal user. So, when one user inputs information or changes information within the electronic contract, it is shared with the involved party. 
     So, if user 1 ( 110 ) and user 2 ( 120 ) does not synchronize with each other, information within the electronic contract cannot be shared. 
     The terminal user ( 100 ) whist inputting information within the electronic contract can provide information in regards to precautions or mandatory input information. 
     At this point, precautions comprise of obligations and rights, so, it can display aspects such as, part time job hours &amp; minimum wage. 
     These types of precautions provide not only legal information, but, examples of issues that are high in frequency in video or text format. 
     For example, when inputting a service contract, ‘Contractor ‘A’ person who is the ordering body &amp; person ‘B’ who is the receiver of the contract and the person who is performing the given task. 
     Please input the relevant person&#39;s personal data ‘A’ OR ‘B.’ Directions will follow. 
     Another example would be in instances such as a labor contract where, ‘the legal minimum wage is since 2009, 4000\ per hour.’ This sort of notification would be present in order to limit unfair and unjust contract procedures. 
     Also, mandatory information input would be aspects such as, real estate transactions where, certified copy of register would be displayed. This type of mandatory information input would be provided with links where you can procure by entering outside collaborated servers. 
     For example, in regards to mandatory information input, when you need to check the registration, you can connect to the registration server link and search and check the required information. 
     Another example is, when you need to check for wire transfer information, you can click the link, and connect to the bank server where you can check the account balance information. 
     The aspects of mandatory information input, depending on the setting, is achieved and can only move on to the next subject where and when the involved party has made a final check, and has input data that confirms that they have made a final check. 
     Through this, this invention can prevent the root of legal conflict in regards to contracts and recognize fraudulent acts. 
     After the completion of the contract, Terminal user ( 100 ) can then, together with the verification information, plus the additional set verification information, confirm and recognize all necessary data. 
     At this point, verification information contains information such as, electronic signatures, official certificate of authorization, etc. 
     Also, verification information is such as, audio or video data that has been recorded OR fingerprint and iridodiagnosis information, visual recognition, blood recognition, etc. All information that can be proof, that the involved party has confirmed or has not confirmed. 
     Furthermore, verification information is present indirectly in order to prevent fraud and plagiarism. For example, terminal user ( 100 ), and its location information. 
     The service server ( 200 ) which deals with various types of electronic contracts provides the user terminal ( 100 ) with contract applications and other things of such nature via wireless or cable connection. 
     The service server receives certification and verification information which verifies the information as a basis and sends that information to the user terminal. 
     At this point, the service server ( 200 ) either, verifies the information independently or, through a collaborated network ( 400 ) by linking systems and can carry out the service. 
     Especially, the service server evaluates the verification as a success when all involved parties have been verified, and then the contract user verification can be stated a success. 
     The database ( 300 ) which deals with various electronic contracts can store contract applications. 
     The collaborated network server ( 400 ) links with the user terminal ( 100 ) to provide information on contract input and files those are necessary. 
     The collaborated network system ( 400 ) deals with information such as, certificate of authorization server, National tax service server, office of Dong server, registry server, bank server, LBS (Location based service) server, etc. 
     In accordance to our exercised record  FIG. 2  shows methods in order to input into electronic contracts. 
     As shown in  FIG. 2 , the electronic contract that is desired to be carried out input, is synchronized with involved party number 1 user terminal ( 110 ), and number 2 terminal users ( 120 ). 
     In accordance to our exercised record  FIG. 3  shows methods to synchronize between terminals. 
     As shown in  FIG. 3 , (a) firstly, terminal user ( 110 ) in order to input electronic contract activates the application, and the necessary input fields are selected by the user. 
     (b) Number 1 terminal user ( 110 ) after receiving the necessary input fields, inputs the number 1 synchronization code into the synchronization code field. 
     At this point, the synchronization code consists of numbers, symbols, texts&#39;, images, etc. 
     (c) The number 1 user terminal ( 110 ) receives contact information for synchronization with number 2 user ( 120 ). 
     Then, number 1 terminal user ( 110 ) upon receiving contact information sends the synchronization code to the number 2 terminal user. 
     (d) When the number 2 terminal user ( 120 ) inputs the synchronization code, number 2 terminal user receives a message in order to be notified of the second synchronization code. 
     When the confirmation message is received, number 1 terminal user ( 110 ) checks whether to be aware if both the first and second synchronization codes are unanimous. When this is done, depending on the results, a notification message will be displayed to be let known if the synchronization. is successful. 
     Also, number 1 terminal user sends a message to notify if the terminal synchronization has been successful to number 2 terminal user. Another message will be displayed if the number 2 terminal user&#39;s synchronization is successful. 
     When the number 1 ( 110 ) and number 2 ( 120 ) terminal user synchronization has been completed, the information can be shared due to the involved parties sending each other input information in regards to the electronic contract. 
     In other words, the number 1 terminal user ( 110 ) actually inputs information in the electronic contract, however, the number 2 terminal user ( 120 ), is sent the information that is being input in real time. 
     However, if terminal user 1 ( 110 ) and terminal user 2 ( 110 ) are not synchronized, the electronic contract information cannot be shared in real time, and the contract is not evaluated as legitimate so the contract is not allowed access to input information in the electronic contract. 
     In other words, when this transpires, a notification will be displayed to once again synchronize number 1 terminal user and the number 2 terminal user. 
     Next, the number 1 terminal user ( 110 ) can select the type of contract at random from the various types of contracts that are stored. 
     At this point, when the contract format is selected by the user terminal ( 120 ), he or she will notify user terminal number 2 ( 120 ) in whereas number 1 terminal user will select the same format. 
     Next, the number 1 terminal user ( 110 ) displays the selected contract and is able to input information that has been provided by the user in the necessary input fields. (S 230 ) 
     Next, the number 1 terminal user  110  is able to check if there are any precautions or mandatory input fields that are required (S 240 ). 
     After checking to see if there are any precautions or mandatory input fields, number 1 terminal user ( 110 ) can display a notification sign that will let the involved party know that there are precautions or necessary input fields that requires input. 
     Next, when the number 1 terminal user ( 110 ) selects a particular notification icon, he or she can display a notification message that is correspondent to the specific matter (S 260 ). 
     In accordance to our exercised record  FIG. 4  shows the electronic contract being put in. 
     As shown in  FIG. 4 , the number 1 terminal user can select a specific notification icon in regards to the precaution or mandatory input field information within the contract. 
     This invention harbors a number 1 icon that notifies precautions, and a number 2 icon that notifies mandatory input fields. 
     (a) A notification icon for precautions and mandatory input field is displayed on the side of the screen for number 1 terminal user in regards to electronic contract input fields. 
     (b) When the number 1 terminal user ( 110 ) selects a notification icon, it will be displayed depending on what the notification is in regards to, either mandatory input fields or precautions. 
     At this juncture, number 1 terminal user ( 110 ) is synchronized with number 2 terminal users ( 120 ), so the notification icons that are displayed towards number 1 terminal user ( 110 ) can be seen by number 2 terminal user  120  as well. 
     At this point, if the user does not confirm that he or she has checked the precautions or mandatory input fields, the electronic contract application de activates itself so that no more information can be put in. In other words, both number 1 and number 2 terminal user needs to check their terminals of the notifications. 
     Next, the number 1 terminal user ( 110 ) can check to see if all the input fields have been put in, in regards to the contract (S 270 ). 
     In other words, when the number 1 terminal user ( 110 ) has confirmed and the contract is complete in regards to this, he or she receives verification information input from the user, and receives location information. 
     Next, number 1 terminal user creates a verification request message and is able to send this to the service server which contains both verification information and location information for verification by the user. 
     In other words, a verification request is sent by number 1 terminal user for verification by the service server which is based on the verification information and location information (S 280 ). 
     Next, number 1 terminal user ( 110 ) can evaluate if the verification process is successful by receiving a message from the service server in regards to if the verification was successful by the service server (S 290 ). 
     Next, when the number 1 terminal user ( 110 ) receives a response message in regards to the verification, he or she can send the complete electronic contract to the service server for registration (S 300 ). 
     The number 1 terminal user ( 110 ) will indeed save the complete electronic contract within the internal memory. 
     In accordance to our exercised record  FIG. 5  shows methods for user verification processes. 
     As shown in  FIG. 5 , if number 1 terminal user wishes to verify with a certificate of authorization, he or she creates a message of request of verification to the service server which includes information in regards to location information and verification information (S 510 ). 
     At this point, number 1 terminal user can receive location information by linking into the LBS server. 
     Next, when the service server receives a request of verification information from the number 1 terminal user, the service server extracts location and verification information from the message received from the number 1 terminal user (S 520 ) and, can send the verification information to the certificate of authorization server (S 530 ). 
     Next, the certificate of authorization server on the basis of the verification information can carry out verification (S 540 ) and send that information to the service server (S 550 ). 
     For example, the certificate of authorization server can inspect to check if the password for the certificate of authorization is unanimous to the password that is set within the terminal and this will conclude phase 1 of the inspection for verification. 
     Next, when the service server concludes successful phase 1 verification, the service server will continue phase 2, verification with the location information as a basis (S 560 ). For example, the service server will conclude the verification as successful when the user&#39;s location is unanimous to the active area set in the terminal. 
     At this point, the user appoints an active area within a certain boundary where he or she works, for example, a house or office and saves this. For instance, this may be an area within a 1 kilometer radius. 
     The number 1 terminal user can check if he or she is within this radius and also check through the terminal if the number 2 terminal user is within the same boundary. 
     Also, the invention will provide information to which it notifies if the number 1 and number 2 terminals are in the same applicable area, and if so, then the 2nd phase verification is evaluated as successful. 
     Next, when the service server is successful with the 2nd phase verification, at least one of the number 2 terminal user who is involved in the electronic contract confirms the verification process (S 570 ). After checking, if all verifications are successful, with the response message he or she can create a response message that confirms the success of the verification and send it to the number 1 terminal user&#39;s terminal (S 580 ). 
     Indeed, the verification confirmation message has to be sent to at least more than one number 2 terminal user (S 580 ). 
     In accordance to our exercised record  FIG. 6  shows the method in which describes user verification. 
     As shown in  FIG. 6 , when an electronic signature is used for verification, number 1 terminal user creates a verification request message which includes location information and verification information to the service server (S 610 ). 
     Next, when the service server receives the verification request message from number 1 terminal user, the service server can extract information from the message which includes location and verification information (S 620 ). 
     Next, the certificate of authorization server can carry out phase 1 verification with the extracted verification information as a basis. 
     For instance, the certificate of authority server inspects if the electronic signature and the terminal set electronic signature are unanimous, and if it is unanimous then the verification is evaluated as successful. 
     Next, when the service server is successful in regards to phase 1, verification, it conducts phase 2 verification with the location information as a basis (S 640 ). 
     For example, checking if the user&#39;s location is unanimous to the active region and if it is then the phase 2, verification is considered successful. 
     At this point, the user designates his or her active region, for example, a house or office in the terminal as the area within where he or she is active. 
     For example, the active region will be within a radius of 1 kilometer. 
     Next, when the service server is successful with the 2nd phase verification, then there is an inspection of a number 2 terminal user who is involved with the electronic signature (S 650 ), with the confirmed results, if all is successful, in response to the verification request message, a response message is created and sent to the number 1 terminal user (S 660 ). 
     Indeed, the service server will send the response message to at least one number 2 terminal user. 
     In accordance to our exercised record,  FIG. 7  shows the specific structure of the user terminal. 
     As shown  100  in  FIG. 7 , the invention consists of, means of communication ( 110 ), means of input ( 120 ), means of control, means of indication, means of storage, etc. 
     The means of communication ( 110 ), transmits and receives various data through cable and wireless networks. 
     For example, the means of communication ( 110 ) transmits and receives information with the user terminal in regards to information such as contract input, requesting and receiving user verification messages from the service server, receiving and transmitting diverse information by linking with the collaborated server. 
     At this point, the means of communication ( 110 ), consists of mobile communication modules, wireless internet modules, short distance communication modules, etc.
