Describe: Append multiple digital signatures to your MS-Word documents. The contents of the documents are assessed prior to signing to enable signature validation based on the unaltered content. Any alterations will invalidate the signature. In addition to using the RSA cryptogrphic digital signature algorithm, a voice sample is incorporated in the signature to verify the user's identity. This voice signature consists of a randomly generated phrase that the signer provides to the voice recognition engine. Once the speech is correctly recognized, the user is then permited to sign the document. The cheapest download securesign for ms word lite edition 101 filters.
