Seal-It employs a patent pending \"Voice Signature\" technology that permits positive identification of the document signatory to prevent fraudulent signatures. Furthermore, in the event the signatory wishes to repudiate the validity of the signature, voice analysis can be employed to ascertain the true identity of the signer. Using digital signal processing algorithms, the software is able to ascertain the degree of likelihood that any two voice samples are correlated.

Seal-It works in conjunction with MS Word to provide a revision history of the document together with any past signatures.

Additionally, an independent timestamp server can be utilized to provide independent corroboration of the actual date and time that the digital signing took place. The freely accessible timestamp server eliminates any uncertainty associated with relying on the users own clock for establishing the precise date and time of signing.
