A method in which user information is transmitted from at least one data source to a processing unit of a learning device. The user information is used, by the processing unit via a machine learner, to generate at least one user model. The at least one user model is adapted via an adaptation of parameters used by the at least one machine learner to generating the at least one user model. The parameters, used by the at least one machine learner for generating the at least one user model, are adapted as a function of at least one predefined rule. The user model generated on the basis of the adapted parameters is used to personalize at least one terminal.

Systems and methods for authorizing rendering of objects in three-dimensional spaces are described. The system may include a first system defining a virtual three-dimensional space including the placement of a plurality of objects in the three-dimensional space, and a second system including a plurality of rules associated with portions of the three-dimensional space and a device coupled to the first system and the second system. The device may receive a request to render a volume of three-dimensional space, retrieve objects for the volume of three-dimensional, retrieve rules associated with the three-dimensional, and apply the rules for the three-dimensional space to the objects.

Techniques for providing data loss prevention, including data exfiltration prevention and crypto-ransomware prevention, are provided. In some embodiments, a slack-space file system is created by using a modified packing algorithm to increase and/or optimize an amount of slack space created by files stored in a standard file system. A program for accessing and indexing the slack-space file system may be stored, and requests by a user to store data on a storage medium of a computer system may cause the information to be stored in the slack-space file system, where it may be protected from destructive malware that operates solely on the standard file system. In some embodiments, sensitive information may be hidden by storing the information in an alternate data stream of a file and by replacing the information in the unnamed data stream of the file with non-sensitive information that may appear to be sensitive.

Nested namespaces for selective content sharing.

A DNS server receives from a receiving email system, a DNS query for an email domain stored at the DNS server, the DNS query including identifying information of a sender of an email. The DNS server extracts the identifying information of the email sender from the DNS query and identifies one of a plurality of delivering organizations from the information. The DNS server determines whether the identified delivering organization is authorized to deliver email on behalf of the email domain. In response to determining that the identified delivering organization is authorized to deliver email on behalf of the email domain, the DNS server generates a target validation record based on the identity of the authorized delivering organization and the email domain, the target validation record including one or more rules indicating to the receiving email system whether the delivering organization is an authorized sender of email for the email domain.

A system for securely producing and using high-entropy security information, such as a password. The system includes a printer, a display device, and a generator computer that is connected to the printer and the display device. The generator computer generates the high-entropy set of characters, (e.g., password), and also generates a machine-readable representation of the high-entropy set of characters, (e.g., a barcode). The generator computer causes the printer to print the high-entropy set of characters and the machine-readable representation on paper, and then deletes the high-entropy set of characters and the machine-readable representation from the system. The high-entropy set of characters, (e.g., password), may be entered into a target computer by scanning the barcode on the paper using a barcode scanner connected to the target computer, which is significantly faster than, and eliminates the human error associated with, typing in a high-entropy set of characters.

An example apparatus includes: at least one memory; instructions in the apparatus; and processor circuitry to execute the instructions to: access a cookie at a client device, the cookie including a priority listing indicative of an order in which beacon requests are to be sent to ones of a plurality of database proprietors; cause a first beacon request to be sent to a first database proprietor server, the first database proprietor server corresponding to a highest priority in the priority listing of the cookie, the first beacon request indicative of access to media at the client device; and cause a second beacon request to be sent to a second database proprietor server, the second database proprietor server corresponding to a lower priority than the highest priority in the priority listing of the cookie, the second beacon request indicative of the access to the media at the client device.

A system and method is disclosed for assuring that networked communications between parties playing a game on a network (e.g., the Internet) are not tampered with by either of the parties for illicitly gaining an advantage over the other party. An initial sequence of tokens (e.g., card representations) for playing the game are doubly encrypted using an encryption key from each of the parties. Accordingly, during play of the game neither party can modify the initial sequence of game tokens during the game. At termination of the game, at least one of the parties can fully decrypt the initial sequence of tokens, and thereby, if desired, compare the played token sequence with the corresponding the initial token sequence.

A method is provided for determining command-to-process correspondence. The method includes identifying, by the hardware processor, initial processes resulting from executions of container immutability change events for each of multiple containers in a cluster, based on an execution time, a process identifier and a process group identifier for each of the container immutability change events. The method further includes checking, by the hardware processor, if an initial process from among the identified initial processes matches an entry in a database that stores external container commands and at least one respective process resulting from executing each of the external container commands. The method also includes designating, by the hardware processor, a particular external command, from among the external container commands stored in the database, as having a correspondence to the initial process, responsive to the initial process matching the at least one respective process resulting from executing the particular external command.
