Abstract: A method and system for authenticating and validating electronic architectural documents. 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 is performed to create an issued file with the digital seal and signature and a cryptographic hash. The issued document is distributed to a recipient, extracted to a local drive, and subsequently accessed for use in an architectural project. The cryptographic hash of the extracted 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 remain visible in the accessed document. If not, the accessed document is not validated and the digital seal and signature are removed from or hidden, indicating the document should not be used.
