Patent number: 11469899Abstract: A system and a method for user authentication and/or authorization, including a passive card to encode a first portion of an authentication or authorization code for a user via capacitive points, and a portable computing device with a capacitive screen to encode a second portion of the code. Each capacitive point is connected to an electronic circuit, being activable by physical contact of the user or with an electrical ground. Once the user has requested access to a specific service or operation, and when at least some of the passive points are activated and the passive card is in contact with the capacitive screen, the device reads the capacitive points, decoding the first portion of the code, and cryptographically signs the decoded portion using the second portion, providing the code, which is used as cryptographic key to grant access to the service or operation.Type: GrantFiled: September 14, 2020Date of Patent: October 11, 2022Assignee: TELEFONICA CYBERSECURITY TECH S.L.Inventors: Sergio De Los Santos Vilchez, Aruna Prem Bianzino, Jose Torres Velasco, Enrique Rando Carrion
