Abstract: A method of packaging and securing computer data permitting the distribution of the secured data electronically from an originating party to any number of recipient parties via any of a variety of data transfer methods including: email, electronic network file distribution ftp, http and other Internet protocols, as well as electronic fixed media CD-ROM, DVD and HD. In order to secure computer data, the electronic data files are packaged as resources, along with an electronic signature, into an executable container file. The container file includes executable instructions for verifying the electronic signature to ensure integrity of the entire container file. Access to individual contents within the executable container file is optionally protected using any of the various types of key access, such as standard cryptographic encapsulations.

Abstract: A spectrum, time and protocol optical power monitor is disclosed. This device utilizes a same photodetector to perform spectral optical monitoring of an incoming optical signal, as well as performing timing and protocol monitoring for preselected wavelength channels. Advantageously the device uses a same passband tunable optical filter for both the spectrum and timing/protocol measurements. The spectral response of the filter passband is deconvolved from the spectral scan in order to achieve improved spectral scan resolution, and the timing and protocol measurements are not degraded by the passband of the filter.
