Abstract: The disclosed method, system, and apparatus are directed to offloading signature generation to avoid security risks, such as the ones described above. In an embodiment, an application library may receive an unsigned request (e.g., an unauthenticated API call) from an application. The unsigned request may include a target service (e.g., cloud computing resource) to which access is requested by the application. The application library may transmit the unsigned request to a signature generator. The signature generator may verify the unsigned request and generate a signature based on credential information accessible to the signature generator. The application library may receive the signature and may add the signature to the unsigned request to form a signed request (e.g., authenticated API call). The application library may transmit the signed request to the target service.

Abstract: Disclosed is a system and method for providing secure access control to an electronic network or device. By limiting the ability of a single administrator to act unilaterally without the agreement and/or notification of further system administrators, the data integrity and security of stored data, such as email accounts, may be enhanced and risk of compromise ameliorated. By permitting multiple administrators acting in a concert of action to access stored data, such as without notification of the email account holder, potential misconduct by email account holders may be audited.

Abstract: Technologies are disclosed for associating a subscriber's subscription profile established with a local media content delivery network, or MSO, with a remote CPE and/or network gateway device, perhaps for example served by the same MSO. One or more techniques may control the delivery of a subscriber's media content, perhaps for example by a media control device. Techniques may include receiving one or more credentials by the media control device, where the media control device is geographically remote from the subscriber's local media content delivery network. A signal may be sent to a media content delivery network device, where the signal may include information corresponding to the credentials. A configuration may be received for the subscriber's local media content delivery network in response to the signal. The configuration may be installed on the media control device. Media content may be delivered by the media control device.

Abstract: Various embodiments described herein are directed towards authenticating calls by using one or more keys associated with a specific user. In examples, the user is the sender of a call. In various embodiments, when a call is made, an identifying payload is encrypted using a private key associated with the user. The encrypted identifying payload is appended to the call data stream. The identifying payload may be decrypted with a public key. In embodiments, the identifying payload may be verified. In various embodiments, further authentication methods may be performed by using an object such as a contactless card to provide one or more components of the identifying payload and/or keys. In embodiments, a connection may be made between the sender and the intended recipient of a call based on the verification of the identifying payload.

A method of securing a solar panel to a tufted geosynthetic land cover system for generation of energy is disclosed.

Abstract: The present invention involves a method for anonymous contact tracing for a user with a mobile device in a location having an associated contract tracing system having a plurality of tokens. The user has a mobile device upon which the user obtains a token from the location and/or the contact tracing system. The mobile device stores the user's space-time coordinate information. There is a recording of space-time coordinate information of each mobile device that is traceable by the contact tracing system in association with one of the tokens. When a user reports the existence of an exposure event, the contact tracing system analyzes the token-coordinate information to determine which of the tokens have been subject to the exposure event. By notifying at least one of the users with an associated token that was subject to the exposure event, those users may also check to see if they have been subject to the same exposure event. The method may be implemented by a server and by software running on a mobile device.

Abstract: Presented are metalworking systems for forming metallic workpieces, methods for making/operating such metalworking systems, and battery module cell tabs bent by a multistage cluster-and-bend press. A metalworking system includes a grouping tool and a contouring tool that both align adjacent a workpiece support structure, such as a base plate of a battery module housing buttressing a stack of battery pouch cells. The grouping tool, which may include a first reciprocating plunger or plunger head, presses together a stack of metallic workpieces to thereby form a workpiece set having a first bend profile and a first length. The contouring tool, which may include a second reciprocating plunger or a pair of plunger fingers mounted on the plunger head, is attached to the grouping tool and bends the workpiece set to a second bend profile, distinct from the first bend profile, and a second set length, shorter than the first set length.
