Okla. Admin. Code § 325:85-15-58
The device shall have the ability to allow for an independent integrity check of the device's software from an outside source. This must be accomplished by being authenticated by a third- party device, which may be embedded within the game software or having an interface port for a third-party device to authenticate the media. This integrity check will provide a means for field testing the software to identify and validate the program. The Independent Testing Laboratory, prior to device approval, shall approve the integrity check method. If the authentication program is contained within the game software, the Manufacturer must receive written approval from the Independent Testing Laboratory prior to submission.
