摘要：A method and system for authenticating and validating electronic architecturaldocuments. A document approved by a licensed architect has the architects digital seal
and signature associated with or inserted into the document file. A hash function isperformed to create an issued file with the digital seal and signature and a cryptographichash. The issued document is distributed to a recipient, extracted to a local drive, andsubsequently accessed for use in an architectural project. The cryptographic hash of theextracted file is compared to that of the accessed filed to determine if they are the same.If the same, the accessed document is validated and the digital seal and signature remainvisible in the accessed document. If not, the accessed document is not validated and thedigital seal and signature are removed from or hidden, indicating the document shouldnot be used.
