A user may be authenticated by a terminal configured to process image data of a two-dimensional code to decode key information, the two-dimensional code comprising a cryptographic binding of user credentials including a low-resolution image of the user's face and optionally user biometric data to database user information stored on a secure server.

Examples of the present disclosure describe systems and methods relating to user-session management in a zero-knowledge environment. When a user authenticates with a computing service to begin a session, a credential-cipher key is used to encrypt the user's authentication credentials, thereby generating session-resume data. The computing service stores the credential-cipher key, such that it is not retained by the user's computing device. Accordingly, when the user resumes the session, a resume request is generated to retrieve the credential-cipher key from the computing service, wherein the request is validated before providing the key. Upon successful validation, the computing service provides the credential-cipher key, which is then used to decrypt the session-resume data and regain access to the user's authentication credentials. The encrypted user data may then be decrypted, thereby obviating the need for the user to re-authenticate, while still retaining the privacy and security benefits of the zero-knowledge environment.

In implementations of dynamic texture for a digital paintbrush one or more computing devices implement a digital paintbrush module to receive a stroke property of a stroke from an input device. The digital paintbrush module determines a weight to apply to a texture image channel that represents an attribute of the digital paintbrush. A magnitude of the weight defines a significance of the attribute relative to another attribute of the digital paintbrush which is represented by another texture image channel. A texture stamp of the digital paintbrush is generated by combining the texture image channel with the other texture image channel. The texture stamp is used to render the stroke of the paintbrush in a user interface of a display device based on the received stroke property.
