Various systems and methods are provided for defining a CAPTCHA generator that is configured to generate CAPTCHA challenges by using at least a first parameter and a first plurality of values associated with the first parameter; defining an adversary program, where the adversary program is configured to automatically attempt to solve the CAPTCHA challenges; performing a first feedback loop that includes generating a first plurality of CAPTCHA challenges, receiving feedback from a group of human users and feedback from the adversary program; and using the feedback received from the human user and the feedback received from the adversary program to modify a weight associated with a first value among the plurality of values in order to generate future CAPTCHA challenges that create less inconvenience for human users but which are more difficult for adversary programs.

Framework to design completely automated reverse Turing tests

An example method includes receiving, at a server, a request for a list of a first group of index records that correspond to stored data, creating a data streaming session with a client, reading an index file and obtaining a list of the first group of index records from the index file, populating a content cache with a signature that corresponds to the first group of index records, creating a sliding window and populating it with the signature and a pointer to a next group of index records, populating an attribute cache with data streaming session information and the sliding window, creating a continuation token which, when received by the server from the client, indicates to the server that the list of the first group of index records has been received by the client.

Method and approach for pagination over data stream with sliding window

An example non-transitory storage medium stores computer-executable instructions for execution by one or more hardware processors to perform operations including: receiving at a server a request for a list of a first group of index records that correspond to stored data; creating a data streaming session with a client; reading an index file and obtaining a list of the first group of index records from the index file; populating a content cache with a signature that corresponds to the first group of index records; creating a sliding window and populating it with the signature and a pointer to a next group of index records; populating an attribute cache with data streaming session information and the sliding window; creating a continuation token which, when received by the server from the client, indicates to the server that the list of the first group of index records has been received by the client.

Mode steering in a wireless communication network includes configuring a list of neighboring access points and their operational modes. If an operational mode of a requesting mobile device can not be supported by the access point, denying the association. If an operational mode of a requesting mobile device matches a highest operational mode of the access point, allowing the association. If the operational mode of the mobile device is not the same as the highest operational mode of the access point, and if any neighboring access point has an available operational mode matching that of the mobile device, denying the association, so as to steer the requesting mobile device to the matching neighboring access point.

Mode steering in a wireless communication network

A communication network comprises a plurality of access points, a plurality of stations wirelessly communicating with the plurality of access points and at least one sensor located at a different location from each of the plurality of access points for improving communication quality in the communication network. The sensor in the communication network senses a communication message transmitted from a source station and destined for a destination access point on a wireless communication channel in the communication network. The sensor further determines a number of retransmissions of the communication message from the source station. The sensor, upon determining that the determined number of retransmissions of the communication message is at least equal to a predetermined threshold, forwards the communication message to the destination access point through the wired medium.
