Abstract: Described is a method and system for controlling usage of software on a computng device An authorization key (16a) is generated as a function of a device string (6a), a unique string (6a) stored in the device, and a software string (10), a unique string (10) stored in software (4) authorized for use on the device The authorization key (16a) is encrypted using a private key and stored in the device Upon a request to use software (4) on the device, the authorization key (16a) is decrypted using a public key corresponding to the private key A test key is generated as a function of the device string and a request software string, a unique string stored in the software for which use has been requested The authorizatin key is compared to the test key When the test key matches the authorization key, usage of the requested software is permitted

Abstract: Described is a computing device (100) comprising an imaging arrangement (112), a processor (116) and an output arrangement (114). The imaging arrangement (11) obtains an image. The processor (116) processes the image to determine a corresponding status of the image as a function of at least one predetermined decodability parameter. The output arrangement (114) displays the image and provides a feedback signal of the corresponding status.

Abstract: A system is provided for selecting a particular barcode on an item that includes multiple barcodes. The system (1) acquires, via a barcode imager, an image of the item within the field of view of the barcode imager, (2) analyzes the acquired image to determine a set of potential barcode fields, (3) determines, using a predetermined criterion (e.g., distance from center of imaged area, type of bar code, etc.), a candidate barcode field from among the set of potential barcode fields, (4) displays a modified image derived from the acquired image, wherein the candidate barcode field is identified within the modified image, and (5) allows the user to initiate a decode session when the candidate barcode field includes the desired barcode. The acquired may be modified to highlight the candidate barcode field in any number of ways, including, for example, superimposing an artificial reticule around the candidate field, superimposing an artificial scan line over the field, altering the contrast of the field, and/or altering the brightness of the field.
