Praetorian Security attests to the protocol's secure-by-design architectureSUMMERLIN, Nev., May 6, 2025 /PRNewswire/ -- FaceTec announced that its digitally-signed biometric barcode UR® Code protocol successfully passed Praetorian Security Inc's rigorous reverse engineering testing process and its risk-informed security assessment as the company continues to expand its industry-leading position in global 3D Face Verification and digital identity software.Praetorian completed reverse engineering analysis of the UR Code's SDK focused on identifying internal hashing mechanisms, encryption keys, and customer PII. During the analysis, Praetorian identified the following:0 Critical Risk Issues0 High Risk Issues0 Medium Risk Issues0 Low Risk Issues0 Informational Risk IssuesComplete attestation letters can be found here:www.urcodes.com/Praetorian_FaceTec_UR_Code_Security_Letter.pdfwww.urcodes.com/Praetorian_FaceTec_UR_Codes_Reverse_Engineering_Analysis_Letter.pdfPraetorian also tested security controls related to robust code obfuscation, like dead code insertion, control flow flattening, and variable, class, and function renaming.UR Codes enable legal identity-issuing authorities to provide machine-readable codes that bind together the legal identity data and biometric face data of a code holder. UR Codes provide similar privacy-protecting biometric security to e-passports, but without the usability and durability problems, or the exorbitant costs of scannable NFC chips.UR Codes are generated by issuing authorities using secure UR Encoder software that runs behind their own firewall. The issuing authority encodes the identity information and feature vector data from the face photo of the person who is being issued the UR Code. A digital signature is then derived and also encoded, verifying that the identity data was truly issued - as encoded - by the listed issuing authority. Using each issuer's unique public/private encryption key pair, the software cryptographically signs each UR Code, making them provably immutable
