Ammunition, such as shotshells used in waterfowl hunting, have indicia applied to substantially all of the external surface to reduce glare normally a problem in conventional ammunition. The indicia, such as a camouflage pattern, is applied either through the use of inkjet printing directly on the shotshell surface or through the application of a heat transfer sleeve to which the indicia has been previously applied. The process of applying the camouflage pattern may be incorporated into the manufacture of the ammunition or may be operable as a standalone process used for pre-manufactured ammunition.

A security core supports a networked banking app for a client application device communicating with a server, such as e.g. a smartphone. It provides a secure environment for the banking app to conduct registration, enrollment, and transaction workflows with corresponding back-end servers on the network. It includes defenses against static analysis, attempts at reverse engineering, and real-time transaction fraud. A principal defense employed is obfuscation of the protocols, APIs, algorithms, and program code. It actively detects, thwarts, misdirects, and reports reverse engineering attempts and malware activity it senses. A routing obfuscator is configured to operate at the outer layer. Previous core designs are retained as camouflage. An internal TLS library is used rather than the OS TLS layer. Cookies are managed internally in the core rather than in the webkit-browser layer.

A camouflage system to be used for both military uniforms and equipment. The system includes specialized means of printing the camouflage system unto fabric. The system can also be used for civilian applications, particularly with sportsman hunters. The system provides camouflage in both the human visible light range and the infrared. The system depends on the use of a macro-pattern resulting from a repeat of a micro-pattern. When applied to fabric, a polyamide-cotton fiber blend has a macro pattern resulting from a repeat of a micro pattern printed on at least one surface. The coloring system used comprises at least four colorings from dyes that in combination produce a percent reflectance value comparable to the negative space of the surroundings near the camouflaged subject. The system functions by a macro pattern being disruptive of the shape of the subject and a micro pattern comprising sharp edge units of a size capable of blending the subject into the background. The relative lightness values and percentages of total pattern are sufficient to produce a percent reflectance of acceptable colors, wet or dry in terms of lightness values compared to current military four-color camouflage. On fabric, the results are achieved by printing A macro pattern that disrupts the sensed shape and a micro pattern with a repeat size that produces the macro pattern. The reflectance of the material is comparable to the negative space surrounding a subject so the subject does not appear too dark or too light (out of place). The variation in the lightness between wet and dry is not greater than 17-28%, achieved during the printing process.

The invention provides an RFID (Radio Frequency Identification Device) mutual authentication method based on a secret key and a cache mechanism, which mainly solves the problems in the prior art that illegal reading, position tracking, eavesdropping, camouflage cajoling and unsafe resetting can not be resisted simultaneously. The achieving steps are as follows: a reader-writer and a tag adopt typical inquire response mechanism, the tag generates two authentication information values, namely beta is equal to hash (rl and Pr0), and sends the authentication information values to the reader-writer, the reader-writer compares received information value with self-computed information value, if the comparison results are same, returning authentication information hash (k' Pr0 and Prl') is sent to the tag through authentication. If the comparison results are different, the information is sent to back-end data base, authentication judgment is conducted by the back-end data base, the returning authentication information hash (k'' Pr0 and Prl'') is sent to the tag, after the tag receives the returning authentication information, authentication is carried out on the reader-writer by comparing the tag with self-computed value hash (k Pr0 and Prl), if the tag and the self-computed value hash (k Pr0 Prl) are same, the authentication is passed. The RFID (Radio Frequency Identification Device) mutual authentication method has the advantages of high safety performance and high execution efficiency, and can be applied to the RFID application context with limited resources and high safety requirements.
