displaying on an interface visited by the authenticated user, the candidate product from a product catalog, such that the candidate product is discoverable by the authenticated user, wherein the candidate product is selected based on matching the set of attributes and preferences of the authenticated user, with the corresponding set of attributes and preferences of the product's target audience; and

providing on the interface visited by the authenticated user, a link using which the authenticated user can access and purchase the candidate product.

5. 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.

6. A method for sharing user preferences, pertaining to one or more products, without having the user reveal their identity, the method comprising processor implemented 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 (S 1 ) corresponding to the user,

generating a Unique-Number (N 1 ) using a random number generation algorithm,

applying a Function (F 1 ) to the Secret-Key (S 1 ) and the Unique-Number (N 1 ) to compute a Public-Key (P 1 ), wherein the Function (F 1 ) is based on Asymmetric Key Encryption, wherein the Function (F 1 ) consumes the Secret-Key (S 1 ) and the Unique-Number (N 1 ) to compute the Public-Key (P 1 ), wherein the Public-Key (P 1 ) is distinct from the Secret-Key (S 1 ),

capturing a set of attributes and preferences of the user pertaining to a category of products associated with one or more business categories,

storing the Unique-Number (N 1 ) on a user device and in a data repository,

storing the set of attributes and preferences in the data repository, and

storing the Public-Key (P 1 ) on the user device and in a peer-to-peer distributed hash-table:

authenticating the user by,

receiving a biometric sample captured from the user in real-time;

processing the biometric sample to generate a Secret-Key (S 2 );

fetching the Public-Key (P 1 ) corresponding to the user from the user device;

computing a Real-Time-Unique-Number (N 2 ) using the Public-Key (P 1 ), the Secret-Key (S 2 ) and the Function (F 1 );

7. The method of claim 6 , wherein the business entity is registered by,

receiving an account creation request from the business entity:

assigning a visibility permission category to the business entity based on the business entity's service category, wherein the visibility permission category set is selected from anonymous, pseudonymous, and public-key visible; and

receiving the product catalog from the business entity.
