A finger sensing apparatus may include a finger sensor having an integrated circuit (IC) substrate, an array of finger sensing elements on the IC substrate, and secure software update circuitry on the IC substrate. In addition, the finger sensing apparatus may include a host platform external from the finger sensor and hosting software associated with the finger sensor. The host platform may cooperate with the secure software update circuitry to authorize an attempted software update.

Finger sensing apparatus performing secure software update and associated methods

A finger sensing apparatus may include a finger sensor including an integrated circuit (IC) substrate, an array of finger sensing elements on the IC substrate, and match circuitry on the IC substrate for performing final finger matching. The finger sensing apparatus may also include a host platform cooperating with the array of finger sensing elements for performing at least one finger prematch function. In addition, the finger sensor and the host platform may implement at least one security function therebetween. The at least one security function may include a watermarking function, and/or an encryption/decryption function.

Finger sensing apparatus using hybrid matching and associated methods

A finger sensing device may include an integrated circuit (IC) substrate, an array of finger sensing elements on the IC substrate, and image watermark circuitry on the IC substrate and cooperating with the array of finger sensing elements for generating finger image data with an image watermark embedded therein. The finger sensing apparatus may also include match circuitry on the IC substrate for performing finger matching based at least upon the image watermark. The array of finger sensing elements may include an array of finger sensing pixels. The image watermark circuitry may distort values from the array of finger sensing pixels to generate the finger image data with the image watermark embedded therein. The watermark circuitry may distort position values from the array of finger sensing pixels.

Finger sensing apparatus using image watermarking and associated methods

A finger sensing apparatus may include an integrated circuit (IC) substrate, an array of finger sensing elements on the IC substrate, and encryption circuitry on the IC substrate cooperating with the array of finger sensing elements for encrypting a user template comprising finger template data and at least one user credential. The at least one user credential may enable another device, such as a host platform, to perform at least one protected operation.

Finger sensing apparatus using encrypted user template and associated methods

This invention features both a device and method for reading machine readable code. The device includes a scanning apparatus, a signal processor and a data processor. The scanning apparatus scans the code and outputs a signal representative of at least a portion of the code. The signal processing means processes each of the signals outputted by the scanning means and further provides signal identification data, including a width and position associated with each of the signals, for each successive scan of the code. The data processing means reconstructs the code from the signal identification data for each successive scan of the code, provided by the signal processing means. The data processing means includes a position aligning means for both selecting an element in a previous scan and calculating the position of that element in a successive scan based upon a calculated offset, and means for aligning the successive scan with the previous scan by means of the calculated offset. The data processing means further includes an alignment verification means for verifying the alignment between the previous scan and the successive scan performed as a result of the means for aligning. The alignment verification means includes means for attempting a predetermined number of additional alignments between the previous scan and the successive scan when the previous scan and the successive scan are not aligned by the alignment verification means.

Scanning device for reconstructing a complete code from scanned segments

This invention features a device and method for reading machine readable code, having a plurality of code elements, on an object. The device includes a scanning apparatus, a signal processor and a data processor. The scanning apparatus successively scans the code and outputs a signal representative of at least a portion of the code, for each successive scan of the code. The signal processor processes each of the signals outputted by the scanning apparatus and further provides signal identification data, including a width and position associated with each of the outputted signals, for each successive scan of the code. The data processor reconstructs the code from the signal identification data for each successive scan of the code, provided by the signal processor. The data processor reconstructs the code by both determining the position of a selected code element for a successive scan and by positionally aligning the selected code element with the corresponding element from a prior scan. In a preferred embodiment, the device of the present invention can simultaneously read and decode a plurality of bar codes affixed to an item which approaches the scan line of the device at any orientation.
