Methods and system for secure transmission and storage of signature data

A method for secure document management, the method comprising:

• generating an encryption key;
• generating a lookup key from a subset of the encryption key;
• generating an access key from an omitted part of the encryption key;
• encrypting a PDF document with the encryption key;
• storing the lookup key in a database;
• presenting the access key with the lookup key;
• finding the encrypted PDF document by the lookup key;
• recreating the encryption key through the provided access key and the lookup key;
• and
• attempting to decrypt and return the PDF document with the recreated encryption key.

A method for secure transmission and storage of signature data, the method comprising:

• creating a lookup key using a sign identification (ID) and an access code;
• generating a contents key using the access code, a session ID, and the sign ID, wherein the contents key is used to encrypt content;
• storing the encrypted content, the look up key, and the contents key;
• sending a link to a client device, wherein the link includes the sign ID and the session ID;
• sending the sign ID and the session ID from the client device to a facilitation webpage;
• receiving the access code at the facilitation webpage;
• sending the sign ID, the session ID, and the access code to a database;
• decrypting the content at the database based on the contents key, the sign ID, the session ID, and the access code;
• capturing a signature corresponding to the content at the client device or the facilitation webpage;
• encrypting the signature using the contents key;
• and
• storing the signature at the database.
