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. The authenticity of the contents of an envelope and the associated signature certificate can be invalidated if unauthorized interaction occurs with the electronic envelope, contents, or signature certificate. Authorized viewers/signers are alerted if such unauthorized interaction occurs. Various levels of authorization can be set for each authorized viewer and signer. Authenticated files can be stored on one or more local computers and transmitted among co-signers and viewers, or stored and accessed remotely, such as on a server accessed via a web site, or some combination of both. Records may be maintained of all interactions with a secured envelope.
