Disclosed are systems, methods, and non-transitory computer-readable storage media for managing content item collections. For example, in embodiment, a client device may receive first user input selecting a content item collection. The client device may generate a graphical user interface for presenting the content item collection. The content item collection may include one or more tiles. Each tile may correspond to a content item embedded into the content item collection and stored by a content management system. The client device may present the content item collection including the one or more tiles. The client device may present, within each of the one or more tiles, an image representing the corresponding content item.

A first party uses a secret key to encrypt information, which is then sent through an untrusted connection to a second party. The second party, however, cannot decrypt the information on its own, and it relays the encrypted information through a secure network. The secure network includes one or more nodes linking the first and second parties through one or more trusted connections (“hops”); each hop features uses of a shared secret key unique to that hop. The first party's connection to the network (domain) receives the information relayed through the secure network by the second party, it decrypts that information according to the secret key of the first party, and it then retransmits the decrypted information to the second party using the secure hops. Techniques are provided for sharing a private session key, federated credentials, and private information.

A method for utilizing a registration authority to facilitate a certificate signing request is disclosed. In at least one embodiment, a registration authority computer may receive a certificate signing request associated with a token requestor. The registration authority may authenticate the identity of the token requestor and forward the certificate signing request to a certificate authority computer. A token requestor ID and a signed certificate may be provided by the certificate authority computer and forwarded to the token requestor. The token requestor ID may be utilized by the token requestor to generate digital signatures for subsequent token-based transactions.

A system for monitoring networked computing devices with integrated electronic data encryption and decryption mechanism is provided. In particular, the system may comprise one or more host applications which may interact with an API layer to transmit encrypted host-related data through a secure data rails to a consolidated data repository. One or more downstream monitoring applications may retrieve and decrypt the host-related data from the consolidated data repository for analysis. In this way, the system may provide a secure, scalable way to monitor host computing systems and flow of sensitive electronic data.

Aspects related to the secure transfer and use of secret material are described. In one embodiment, an encrypted secret key and encrypted revocation data are imported into a trusted execution environment and decrypted with private provider and vendor keys. In this manner, a provider of cryptographic processes is not exposed to the secret key or revocation data of a customer, as the secret key and revocation data are decrypted and stored within the trusted execution environment but not accessed in an unencrypted form. In turn, the provider can receive various instructions to perform cryptographic operations on behalf of the customer. Based on the outcome of a revocation check using the revocation data, the instructions can be performed by the trusted execution environment.

The present disclosure relates to the field of computer technologies and it discloses a method for encrypting a picture performed at a sending device, the method including: obtaining, by a sending device raw data of a to-be-encrypted picture, a first key, a second key, and location information that is used for adding disturbance data to the raw data; generating the disturbance data, and adding the disturbance data to the raw data according to the location information, to obtain first data; encrypting the first data by using the first key, to obtain the second data, and encrypting the first key and the length of the disturbance data by using the second key, to obtain first encrypted data; and sending the second data, the first encrypted data, and the second key to a receiving device.

Virtual smart card system includes a virtual smart card server (VSS) which controls access to content respectively associated with a plurality of virtual smart cards. A remote client computer system includes a system level agent which establishes the client computer machine to the VSS as a trusted computer system. A user level agent at the client computer system responds to a request for a virtual smart card operation by causing the client computer system to obtain user authentication information, negotiate with the system level agent to obtain a cookie, and initiate a request to the VSS for the virtual smart card operation. The VSS will perform the virtual smart card operation provided that a security policy is satisfied and will communicate the results to the user level agent.

The techniques and systems described herein are directed to providing targeted, secure software deployment in a computing system. An identity of the computing device can be determined and verified using a trusted platform module (TPM) of the computing device, and a software update can be expressly configured to operate solely on the computing device. Further, a configuration of the computing device can be ascertained using platform configuration registers (PCRs) of the TPM to determine that the computing device has not been modified from a trusted configuration. For example, if malware or unauthorized software is operating on the computing device, the software update may be prevented from being installed. Further, the software update can be targeted for a particular computing device, such that when the software update is received at the computing device, the software update may not be duplicated and provided to an additional, unauthorized device.

Methods and apparatus for activating a purchased or previously deployed device by a subscriber. In one embodiment, activation includes authenticating the device to a service provider or carrier, and providing the device with data necessary for enabling the service to the device. In one variant, a user device is activated at a retail store, with the assistance of a carrier representative. In another variant, user equipment is activated via a communications network without the assistance of a representative. In yet another variant, the user equipment is activated via the Internet without the assistance of a representative. The provision of access data includes pre-assigning eSIM from a population of unassigned eSIMs to certain devices for various carrier networks. Alternatively, the eSIM may be assigned on an as-needed basis. Unassigned and/or unused eSIMs can be released (or sold back to the vendor) and/or reused. Solutions for eSIM backup and restoration are also described.

A method for users of devices including mobile phones and computers to engage in encrypted communications with other devices using asymmetrical key exchange technology, involving the user of a device first creating a password and then at a later time re-entering that password on the device, with the result that when the password is re-entered the device is able to decrypt a set of software components that are required for a fresh session of encrypted communications.
