A method, system and computer program product for partitioning the binary image of a software program, and partially removing code bits to create an encrypted software key, to increase software security. The software program's binary image is partitioned along a random segment length or a byte/nibble segment length, and the code bits removed, and stored, along with their positional data in a software key. The software key is encrypted and is separately distributed from the inoperable binary image to the end user. The encrypted key is stored on a secure remote server. When the end user properly authenticates with the developer's remote servers, the encrypted security key is downloaded from the secure remote server and is locally decrypted. The removed code bits are reinserted into the fractioned binary image utilizing the positional location information. The binary image is then operable to complete execution of the software program.

An angle sensor 302 in a digital or film camera senses the absolute or differential azimuth angle of the camera. At the time of first image capture, the camera azimuth angle H1 is latched in storage register 304. A constant angle value K degrees is added to this stored angle H1, and the sum is then a target angle value H1+K. As the camera continues to rotate, angle value H is compared in comparator 306 to H1+K, and when substantially equal, a command is generated activating shutter 318 to capture the second image and store the current azimuth angle H2 in storage register 304. An alternative embodiment stores a reference image portion pixel data set from a reference image portion 404 of the first captured image. As the camera rotates, a new pixel data set from a sampled image portion on the opposite side of the field of view is captured every few degrees, and is compared to the stored reference image portion pixel data set. When the camera has rotated such that the sampled image portion pixel data set substantially equals the reference image portion pixel data set, a peak in correlation occurs which generates a shutter activation command to capture the next image in the sequence. At the substantially same time a new reference image portion pixel data set is stored.

A method, system and computer program product for preventing execution of pirated software. A file is loaded on an end user's computer containing a binary image that is generated by removing one or more code bits from an executable code. A request is sent to a remote server to return a software key required for execution of the executable code from the binary image. The software key is downloaded to the end user's computer on which the binary image is loaded. One or more bits from the software key is inserted into the appropriate location of the binary image to regenerate the executable code. The executable code is enabled for execution on the end user's computer only following the embedding of the one or more bits.
