System and method for affixing a signature using biometric authentication
A system and method for affixing a signature using biometric authentication, is described herein. The system is configured for registering a user by receiving a set of biometric samples of the user, processing the set of biometric samples to compute a Secret-Key (S1) corresponding to the user, generating a Unique-Number (N1) using a random number generation algorithm, applying a Function (F1) to the Secret-Key (S1) and the Unique-Number (N1), to compute a Public-Key (P1), receiving a document signing request from an application. Once the user is registered, the system is configured to receive a biometric sample from the user in real-time and compute the Secret-Key (S2) for authenticating the user. Once the user is authenticated, the system may capture the user's approval to affix the user's signature to the document and transmit the user's signature to the application upon successful authentication of the user.
1. A system for affixing a signature using biometric authentication, the system comprising:
a processor and a memory coupled to the processor, wherein the processor is configured to execute instructions stored in the memory for:
registering a user by,
receiving a set of biometric samples of the user, corresponding to one or more biometric factors,
processing the set of biometric samples to compute a Secret-Key (S1) corresponding to the user,
generating a Unique-Number (N1) using a random number generation algorithm,
applying a Function (F1) to the Secret-Key (S1) and the Unique-Number (N1) to compute a Public-Key (P1),
storing the Unique-Number (N1) on a user device and in a data repository, and
storing the Public-Key (P1) on a storage device;
receiving a document signing request from an application, wherein the document signing request corresponds to a document to be signed;
initiating a first authentication process by,
receiving a biometric sample captured from the user in real-time,
processing the biometric sample to generate a Secret-Key (S2),
fetching the Public-Key (P1) corresponding to the user from the user device,
computing a Real-Time-Unique-Number (N2) using the Public-Key (P1), the Secret-Key (S2) and the Function (F1), and
authenticating the user based on comparison of the Real-Time-Unique-Number (N2) with the Unique-Number (N1) stored on the user device;
displaying contents of the document to be signed by the user upon successful first authentication of the user;
capturing the user's approval to affix the user's signature to the document;
initiating a second authentication process; and
transmitting the user's signature to the application upon successful first authentication and second authentication of the user.
2. The system of claim 1 , wherein the one or more biometric factors correspond to fingerprint, face, voice, retina, and palm vein, wherein the set of biometric samples are captured by the user device.
3. The system of claim 1 , wherein the application is a web based application or a mobile application.
4. The system of claim 1 , wherein the document signing request is generated upon scanning a machine-readable code.
5. The system of claim 4 , wherein the application is configured to record the user's signature, wherein the user's signature represents a promise to abide by the terms and conditions specified in the document.
6. The system of claim 1 , wherein the second authentication process is triggered instantaneously upon capturing the user's approval through the user interface, wherein the second authentication process is the same as the first authentication process.
7. A method for affixing a signature using biometric authentication, the method comprising steps of:
registering a user by,
receiving a set of biometric samples of the user corresponding to one or more biometric factors,
processing the set of biometric samples to compute a Secret-Key (S1) corresponding to the user,
generating a Unique-Number (N1) using a random number generation algorithm,
applying a Function (F1) to the Secret-Key (S1) and the Unique-Number (N1) to compute a Public-Key (P1),
storing the Unique-Number (N1) on a user device and in a data repository, and
storing the Public-Key (P1) on a storage device;
receiving a document signing request from an application, wherein the document signing request corresponds to a document to be signed;
initiating a first authentication process by,
receiving a biometric sample captured from the user in real-time,
processing the biometric sample to generate a Secret-Key (S2),
fetching the Public-Key (P1) corresponding to the user from the user device,
computing a Real-Time-Unique-Number (N2) using the Public-Key (P1), the Secret-Key (S2) and the Function (F1), and
authenticating the user based on comparison of the Real-Time-Unique-Number (N2) with the Unique-Number (N1) stored on the user device;
displaying contents of the document to be signed by the user upon successful first authentication of the user;
capturing the user's approval to affix the user's signature to the document;
initiating a second authentication process; and
transmitting the user's signature to the application upon successful first authentication and second authentication of the user.
8. The method of claim 7 , wherein the one or more biometric factors correspond to fingerprint, face, voice, retina, and palm vein, wherein the set of biometric samples are captured by the user device.
9. The method of claim 7 , wherein the application is a web-based application or a mobile application.
10. The method of claim 7 , wherein the document signing request is generated upon scanning a machine-readable code.
11. The method of claim 10 , wherein the application is configured to record the user's signature, wherein the user's signature represents a promise to abide by the terms and conditions specified in the document.
12. The method of claim 7 , wherein the second authentication process is triggered instantaneously upon capturing the user's approval through the user interface, wherein the second authentication process is the same as the first authentication process.
