Summary This paper presents new approach for creation of advanced multilevel user authentication protocols using hybrid CAPTCHA codes. Such codes will define a new class of cognitive CAPTCHAs, which, during verification, require from users special skills and knowledge, which is necessary for proper authentication. This way of authentication may be oriented for providing data access only for a special group of experts or trusted users who represent particular expertise areas and have special perception abilities and knowledge. For presented authentication protocols, possible examples of applications will be presented, and security features will be described. Presented innovative verification codes will considerably expand the existed security protocols toward the creation of cognitive‐based approaches oriented for user authentication. Such approaches define novel classes of cryptographic procedures, which can use personal features and perception skills.
