User exposure to media items is detected and measured. A mobile client device carried by a user digitally samples the audio environment of the user on a regular basis. These samples are transformed into a stream of data signatures and compared with reference media items to detect user exposure to the reference items. Purchase behavior following exposure to selected media content items can be detected and tracked as well, so as to gauge effectiveness of media items such as advertisements.

Improved electronic gaming apparatus, including a cabinet for housing video and sound generating electronics, coin-handling and pay-out mechanism and a video display screen. The display screen is substantially taller than it is wide and may have a touch screen associated therewith. Although the displayed video presentation may take any form, the display may include graphics replicating the standard play board at top, game board in middle, and principal user input interface below.

Method and apparatus for providing authenticated, secure, on-line communication between remote locations including a user terminal adapted to enable a player in one location to remotely communicate via a communications medium such as the Internet with a gaming host in another location. Location of the remote user terminal, the host server and universal time are determined using means for accessing signals generated by geostationary navigational transmitters, such as in the global positioning satellite (GPS) system. Player authentication (identity verification) is determined by use of a personal identification number (PIN) and an electronic signature verification service. Security of communication is accomplished through use of a public-key/private-key encryption system. The remote user terminal may be comprised of one or more discreet components adapted to be used with a laptop or desktop personal computer (PC), or may be embodied in a stand alone or self-contained single unit that is portable and communicates via radio waves, telephone lines or the Internet to a host server.

The electronic casino gaming system consists of several system components, including a microprocessor (), a main memory unit () that is typically a random access memory, and a system boot ROM (). Also included in the electronic casino gaming system are a non-volatile RAM (), a mass storage unit (), a disk subsystem (), and a PCI bus (). The disk subsystem () preferably supports SCSI-2 with options of fast and wide. A video subsystem () is also included in the electronic casino gaming system and is coupled to the PCI bus () to provide full color still images and MPEG movies.

Electronic gaming apparatus having authentication data sets

Authentication of a casino game data set is carried out within the casino game console using an authentication program stored in an unalterable ROM physically located within the casino game console. The casino game data set and a unique signature are stored in a mass storage device, which may comprise a read only unit or a read/write unit and which may be physically located either within the casino game console or remotely located and linked to the casino game console over a suitable network. The authentication program stored in the unalterable ROM performs an authentication check on the casino game data set at appropriate times, such as prior to commencement of game play, at periodic intervals or upon demand. At appropriate occasions, the contents of the unalterable ROM can be verified by computing the message digest of the unalterable ROM contents and comparing this computed message digest with a securely stored copy of the message digest computed from the ROM contents prior to installation in the casino game console.
