Title: Methods and apparatus for efficient computation of one-way chains in cryptographic applications
Inventor: JAKOBSSON BJORN MARKUS
IPC: G09C1/00
Filed: 2002-04-15
Abstract: Techniques are disclosed for efficient computation of consecutive values of one-way chains and other one-way graphs in cryptographic applications. The one-way chain or graph may be a chain of length s having positions v i=1, 2, ...s each having a corresponding value vi associated therewith, wherein the value vi is given by vi=h(vi+1), for a given hash function or other one-way function h. An initial distribution of helper values may be stored for the one-way chain of length s, e.g., at positions given by i=2j for 0 j log2 s. A given one of the output values vi at a current position in the one-way chain may be computed utilizing a first helper value previously stored for another position in the one-way chain between the current position and an endpoint of the chain. After computation of the given output value, the positions of the helper values are adjusted so as to facilitate computation of subsequent output values. Advantageously, a storage-computation product associated with generation of the output values of the one-way chain has a complexity O((logs)2).

Title: The use of cross-protection to identify novel vaccine candidates for infectious agents
Inventor: CHERWONOGRODZKY JOHN W
IPC: C07K14/195
Filed: 2004-01-21
Abstract: This invention discloses methods for identifying Francisella tularensis vaccine candidates. It enables identification of novel vaccine candidates and quality assurance for vaccine batches, assessment of protection in vaccinates and identification of the infecting agent in vaccinates. Mice were first vaccinated with Brucella abortus O-polysaccharide (OPS) vaccine. These animals were then given 10 LD50s of F.  tularensis live vaccine strain (LVS). Sixty percent (60%) of the vaccinated mice survived the multiple lethal doses. Sera were collected from these surviving mice and the antibodies were used to probe supernatant and cell lysates of live F. tularensis LVS  cultures. Several F. tularensis components were identified only by the noted "survivor"  antisera. Of these identified proteins, enzyme digestions and chemical oxidation suggest post-translational modifications of some proteins e.g. a 52 kDa glycoprotein, a 45 kDa lipoprotein and a 19 kDa nucleoprotein. The 52 kDa component caused nitrous oxide induction in tissue cultures at low concentrations, cell death at high concentrations. Vaccination with this gave partial protection while addition of other components acted synergistically to give enhanced protection from 250 LD50s of F. tularensis LVS.

Abstract: A method for demultiplexing digital video data which originates from multipl e sources in which the multiplexed images are not indexed nor is there identification information provided to differentiate sources. The sources ar e generally cameras which may be stationary cameras or moving cameras that rotate as are commonly used in the surveillance industry. A first set of digital video data representative of a first image is retrieved from a memor y source or from a video tape. The first set of digital video data is stored t o a memory location associated with a first source. The first set of video dat a is also identified as representative video data of the first source. A secon d set of digital video data representative of a current image is then retrieve d. A difference ratio is calculated using the representative digital video data and the current set of digital video data. If the difference ratio is above a threshold, a display query requiring response for classifying the current digital video data as belonging to an identified source or originating from a new source is presented to a user of the system. If a response is received indicating that the current set of digital video data is associated with a n ew source, the current set of digital video data is stored to a second memory location associated with the second source. This current set of digital vide o data is then identified as the representative video data for the second sour ce.
