Abstract
In Secure-Asynchronous Signing, when a record is inserted into a collection of records by a user, the user specifies a registered digital certificate to associate with the record. The digital certificate was previously registered by the user. To subsequently sign a record, the user provides a digital signature. The digital signature is validated using data in the record and a public key of the digital certificate that was associated with the row. Invalid digital signatures are detected and rejected regardless of how long afterward the attempt to sign the row occurs after inserting the row.
