Abstract: A search request received from a user is converted to a search request integer value using an operational portion of a chip in network equipment. The search request integer value is compared to representative data integer values that were previously converted from a dataset of search terms using the operational portion, the representative integer values being stored on the chip. If the comparing is successful, a signal is transmitted to a second database, the signal being used to determine a message to be transmitted to the user that corresponds to the representative data integer.

Abstract: A method of unlocking usable memory space of a portable memory device, such as a flash drive, includes connecting the portable memory device to a network access device, such as a computer. The network access device executes a control program and accesses a website through the network access device by execution of the control program. A specific task is executed at the website, which sends an unlocking code upon completion of the task. The usable memory space of the portable memory device is unlocked in response to receiving the unlocking code at the network access device.
