Abstract: In one embodiment, a method includes a system receiving a request from a user's device, the request being directed to a first host. The system may generate a key, a verification token, and an encrypted key. The system may transmit the verification token and the encrypted key to the device from the first host, and transmit instructions configured to cause (1) the verification token to be stored as a cookie associated with the first host, and (2) the device to transmit the encrypted key to a second host. The system may receive a second request comprising the encrypted key from the device, and decrypt it to obtain the key upon determining that the encrypted key was not previously decrypted. The system may transmit the key to the device from the second host, and instruct the device to store the key as a cookie associated with the second host.

Abstract: A method for live database schema tree change, comprising: (a) providing a computerized database comprising: a parent database table and a child database table having a column configured to reference the parent database table; and (b) while the computerized database is live, operating a database management system (DBMS) in control of the computerized database, to: create an intermediate database table having a column configured to reference the parent database table; in the child database table: create a column configured to reference the intermediate database table, insert an identifier of the intermediate database table into all fields of the column configured to reference the intermediate database table, and overwrite all fields of the column configured to reference the parent database table with data from the fields of the column configured to reference the intermediate database table.

Abstract: A method for changing targeting criteria in a social advertising platform. The method includes receiving data from a user. The data comprises one or more social metric rules, and targeting criteria values of one or more ad entities in a social advertising platform. The method comprises retrieving, automatically, from the social advertising platform, one or more baseline social metrics based on the targeting criteria values. The method includes periodically retrieving, automatically, respective present social metrics from the social advertising platform. The method includes periodically computing, automatically, a compliance value based on the present social metrics, the baseline social metrics, and the social metric rule(s). The method includes periodically comparing the compliance value to a predefined threshold and based on the comparison, instructing the social advertising platform to change one or more of the targeting criteria values. The method includes storing the changed targeting criteria values.

Abstract: A system, method and non-transitory media containing instructions for managing a next engagement in a system comprising a memory storing a database of collected users' paths to conversion, the system including a processor operatively coupled to the memory to obtain a pattern comprising one or more interactions, with respect to a user, map the obtained pattern to paths in the database and selecting the paths characterized by a likelihood value fitting a predefined condition, to yield matched paths, select a preferred path from among the matched paths using parameters, and determine an action for the next engagement using business-related criteria, thereby influencing said user to choose a next action corresponding to the selected preferred path.
