Personal Code is a binary sequence of data that securely contains the identity of a person, thing or process (Biographical data, Photograph, biometrics, PIN or password, secret questions, etc.) and can be verified by a third party without requiring connectivity / internet or consulting a database, avoiding the repudiation of the issuer, the falsification or alteration of the information and thus, through biometrics avoid identity theft. Thanks to the use of data compression algorithms, they can be stored in very low capacity storage media such as: two-dimensional codes, electronic chips, etc. and be transmitted by means of communication with speed, battery, distance or bandwidth limits such as: BTL Bluetooth, NFC “Near Field Communication”, etc., in all types of print media and / or totally digital environments.



Use of cryptography and digital signatures that guarantee the confidentiality, integrity and authenticity of the data and consequently the NON REPUDIATION of the same

Data sovereignty (adherence to the GDRP regulation), the user is the custodian of their personal data

Protection against falsification and alteration of documents

Protection against identity theft

Validation through mobile devices (iOS and Android)

Immediate availability for replacement and reissue

Long document durability for a long useful life

Offline solution; does not require internet connectivity or mobile data for document validation

Distributed processing: since the verification is 1:1 within the same device, the concurrency and the use of centralized servers are avoided, achieving greater efficiency

Multiplatform solution: the validation of PERSONAL CODE does not require a specific technology

PERSONAL CODE specializes in different sectors

System applied to the health sector with citizen information and their mobility services. Protecting the sovereignty of identity and personal data which are guarded by their owners, not by the institution.
