Abstract: A method and system for securely transmitting data from a sender to a receiver wherein a private lock is created by a receiver. The private lock is freely distributable while the key remains with the receiver. To receive encrypted data, the lock is sent to the sender who uses the lock to encrypt data. The sender sends the encrypted data to the receiver. When the receiver receives the encrypted data, he can decipher the message using his own key. In cases where there are multiple intended recipients, each recipient sends their lock to the sender and the sender encrypts the same data with each of the locks. The sender then sends the encrypted data to each of the recipients. Each recipient uses their own key to access the data. In some instances, the locks will be recognizable and each receiver will be able to identify his own lock while in other instances the locks will not be recognizable and the user will not know how many locks are on the data or the types of locks that are being used.

Abstract: This present invention includes a method for capturing and transmitting data captured from a writing instrument in a secure manner. More specifically, the biometric information collected from the pen is coupled with at least one additional data point for encryption. The user initially uses the pen to create a signature which is converted into an encrypted reference value in accordance with the present invention. When authentication is desired, the user uses the same or similar pen to create a signature which again is converted into an encrypted data value. Thereafter, the encrypted reference value is compared to the encrypted data value to determine if the values substantially match. There is not need to retain the original reference signature, thereby enhancing the security of the overall system.

Abstract: Presented are systems and methods of signature authentication. A signer employs a bio-pen to electronically sign a file. Signature data corresponding to the bodily movements associated with producing the signer's signature are collected and authenticated against a standard. If the signature data is authenticated a signature certificate including the authenticated signature data is generated and assigned to an electronic envelope. Additional data, such as a bio-pen serial number, time stamps, and user identifier can be collected and used for authentication and inclusion in a signature certificate. Assigning the signature certificate secures the contents of the electronic envelope and signature certificate. An electronic envelope may include any number of files of various types. The systems and methods of signature authentication may accommodate more than one signer of an electronic envelope.
