AI Technical Summary
Technical Problem
In the existing technology, user devices cannot simultaneously guarantee security and convenience when providing secure data access, especially in terms of vulnerabilities in unauthorized remote user attacks and replay attacks.
Method used
By employing a restricted CAPTCHA system combined with proximity sensing, the uniqueness of CAPTCHAs and proximity detection are ensured through the generation and verification of CAPTCHAs and the use of inter-module communication and shared secrets, thus preventing unauthorized access.
Benefits of technology
It improves the security of secure data access, prevents unauthorized remote access and replay attacks, simplifies system design, and reduces reliance on trusted time sources.

Abstract
An apparatus is disclosed that allows access to secure data. A first module is arranged to generate a limited use authentication code and to make the authentication code available to a user. A second module and a third module are arranged to communicate whereby detection of the third module in proximity to the second module is allowed. A fourth module is arranged to receive the authentication code via user input. The apparatus is arranged to allow access to the secure data in dependence on the fourth module receiving a valid authentication code generated by the first module and the third module being in proximity to the second module.
