Abstract: A system for controlling access to hosted services using computer generated question answer sets is described. The question answer sets are generated and include relationships which are designed to distinguish between human and automated system interpretation through the inclusion of a dynamically established transformation of characteristics in relation to objects described in the question answer sets. The dynamically established transformation provides an additional defense against malicious neural networks used to overcome mechanisms for distinguishing between humans and automated systems. Corresponding methods and devices are contemplated. In an additional embodiment, a decoy set of answer sets are also established to maintain a blacklisted set of suspected automated systems.

Abstract: An authorization access system and method of minimizing unauthorized access to a resource are provided. The authorization access system comprises at least one processor, and a memory storing instructions which when executed by the at least one processor configure the at least one processor to perform the method. The method comprises assigning a first risk score to application programming interface (API) traffic associated with a user device and/or user behaviour pattern observed prior to an API gateway, assigning a second risk score to the API traffic associated with the user device observed at the API gateway, assigning a third risk score to the API traffic associated with the user device and/or back end service responses observed after the API gateway, and performing an authorization action based on any of the first, second or third risk scores.

Abstract: Computer implemented methods and systems are provided for controlling access to one or more computational resources by discriminating between a human user or an automated process. An example system comprises one or more computer processors operating in conjunction with computer memory and data storage to render a set of question images including at least two images having one or more inter-image visually ascertainable relationships, and at least one image having one or more intra-image visually ascertainable relationships, the inter-image visually ascertainable relationships and the intra-image visually ascertainable relationships having one overlapping visually ascertainable relationship.
