A retail environment having retail terminals with data entry point devices selectively encrypts input received by the data entry point devices and passes the encrypted data to a security module. The selective encryption is based on whether or not sensitive or confidential information, such as a personal identification number (PIN) associated with a debit card, is being input. To prevent hacking of the software of the retail terminal, content destined for display on the retail terminal is authenticated prior to display. In this manner, the retail terminal may be assured that confidential information is input only when desired, and thus may be encrypted only as needed.

The present invention discloses a thermosetting resin composition including: a bi-functional or multi-functional epoxy resin, a SMA uses as a curing agent, an allyl phenol such as diallyl bisphenol A used as a co-curing agent and a toughening agent a low-bromine or high-bromine BPA epoxy resin or tetrabromobispheno A (TBBPA or TBBA) uses as a flame retardant agent, and an appropriate solvent.

The invention belongs to the technical field of digital watermark technologies, and provides a method and a system for authenticating image contents. According to the method and system, an AMBTC (Absolute Moment Block Truncation Coding) algorithm is utilized for guiding the embedding and extraction of a digital watermark, and the parity of a low mean value and a high mean value of each pixel block is correspondingly equal to a to-be-embedded 2-byte watermark by adjusting the pixel value of each pixel in each pixel block of the input image.

Polyamines with varying chain-lengths were evaluated for antimicrobial activity in order to test the hypothesis that these bis-cationic amphipathic compounds may also bind to and permeabilize intact Gram negative bacterial membranes. The compounds were found to possess significant antimicrobial activity and mediated via permeabilization of bacterial membranes. Homologated spermine, bis-acylated with C₈ or C₉ chains was found to profoundly sensitize E. coli to hydrophobic antibiotics such as rifampicin.

A static analysis tool is augmented to provide for enhanced security vulnerability determination from generated code traces. According to this disclosure, a multiple sequence alignment is applied to a set of traces generated by static analysis of application source code. The output of this operation is an alignment result that simplifies the traces, e.g., by representing many common nodes as a single node. In particular, the sequence alignment identifies entries in the alignment result that represent at least one code execution path that multiple traces in the set of traces include. A call graph can then be output that includes the at least one code execution path identified, and that call graph can also be simplified by applying a compression portions of the traces that are used to generate it. Using multiple sequence alignment and simplified call graphs enable a user to identify security vulnerabilities more efficiently.
