  • Publication number: 20200043059
    Abstract: Systems and methods for advertising, and, more particularly, systems and methods for managing ephemeral locations in a virtual universe. A method for managing ephemeral locations in a virtual universe (VU) includes causing a computer infrastructure to: render an ephemeral location upon a triggering in the VU; teleport a VU user avatar to the ephemeral location; permit the user avatar to interact in the ephemeral location; teleport the user avatar out of the ephemeral location; and un-render the ephemeral location.

  • Patent number: 10356153
    Abstract: A method for transferring session data includes receiving a hypertext transfer protocol (HTTP) request that includes user credential data from a client computer program; determining whether to apply a filter that includes data inclusion condition(s) or data exclusion condition(s) to data pertaining to a session between a first application and the client computer program; storing a data structure containing the user credential data in response to the client computer program not meeting the data inclusion condition(s) or the session meeting the data exclusion condition(s); transmitting an HTTP response that includes an identifier of the data structure and an identifier of a second computer program function, which utilizes the identifier of the data structure to retrieve data to authenticate the client computer program; and erasing the data structure from the memory to prevent replay attacks.

  • Patent number: 10318978
    Abstract: Embodiments of the present invention provide an approach for enhancing computer interaction challenge-response tests (e.g., Completely Automatic Public Turing Test to Tell Computers and Humans Apart, or CAPTCHA). Furthermore, embodiments of the present invention provide an approach for introducing advertising in such challenge-response tests, such that users are presented with opportunities to learn about or reinforce brands. In a typical embodiment, when a user attempts to access content (e.g., web content), the user will be presented with a CAPTCHA test. The CAPTCHA test typically includes an advertisement (e.g., logo, label, etc.) and an associated question for the user to answer. Along these lines, the advertisement is generally selected based on the user's demographics (e.g., interests, gender, age, etc.). If the user successfully responds to the question and/or responds within a certain amount of time, a reward can be determined (e.g.
