Abstract: A portable electronic device for authentication and encryption communicably attached to a computer system is provided. The portable device may generate and automatically output authentication data for a plurality of accounts on request by a user. The output generated by the device is variable and customizable data that matches the data required by websites, applications, and other computer based systems to function as a universal authentication device. The device may include means to encrypt, decrypt, sign, verify and hash data including emails, images, documents and other files on request by a user. The device further having means to require physical user presence in order to generate authentication, encryption, decryption, signature, verification or hash data. The device includes a keypad having a plurality of buttons, a power and data connector, a data processing unit, a keyring hole, a light emitting diode, and a reset button.

Abstract: A tamper respondent apparatus having an enclosure comprising of an electrically conductive material layer configured to substantially form continuous electrically conductive paths, an electrically non-conductive material layer forming an outer layer configured to substantially insulate said electrically conductive material layer, an electrical connector at a corner of an underside surface of said enclosure, whereby said conductive material layer and non-conductive material layer are extruded or deposited in successive layers by a three dimensional printer, wherein said electrically conductive material layer forms an inner layer of said extrusion of said three dimensional printer, and wherein a cohesive strength of said conductive material layer is configured to be less than a cohesive strength of said non-conductive material layer.

Abstract: A three-dimensional printing apparatus configured to print a three-dimensional object is provided. The three-dimensional printing apparatus may include a print head that extrudes or deposits an electrically non-conductive material and an electrically conductive material. Said electrically conductive material may be configured to substantially form continuous electrically conductive paths and an electrically non-conductive material may be configured to substantially insulate said electrically conductive material. In one example, the three-dimensional printing apparatus may be employed to print a three-dimensional object that may be used to form an electrical circuit. In another example, the three-dimensional printing apparatus may be employed to print a three-dimensional object that may comprise features that may reduce electromagnetic interference (“EMI”).
