A backend computing system may receive first data from a first computing system, where the first data may be an encrypted version of second data that has been generated at the first computing system based on a command at the first computing system. The backend computing system may identify a second computing system different than the first computing system based on a status of the second computing system, and may send the first data to the second computing system to enable the second computing system to decrypt the first data and perform a function with respect to the second data. In some embodiments, the first computing system may generate padded data by adding data to the second data, and send the padded data to the backend computing system. In some embodiments, the first computing system may send random data to the backend computing system.

Techniques for encrypting keyboard data prior to its being received by an operating system of an endpoint device, reducing the possibility of unencrypted keyboard data being logged by a keylogger application running on the endpoint device. The techniques employ an encryption filter communicably coupled between a keyboard and the endpoint device. The encryption filter receives unencrypted keyboard data from the keyboard, encrypts the keyboard data, and provides the encrypted keyboard data to the operating system of the endpoint device. The techniques can be employed in association with a back-end data processing center of a security standard compliant organization, which can receive the encrypted keyboard data from the endpoint device, and decrypt the keyboard data for use on a host system. In this way, access and/or storage of unencrypted keyboard data at the endpoint device can be avoided.

Encryption of keyboard data to avoid being read by endpoint-hosted keylogger applications

Just in time delivery of a consistent user profile to overlapping user sessions, where a first user session issues a request for a first file of a user profile to a server agent. Upon receiving the request, the server agent retrieves the first file from a base user profile, and just in time delivers the retrieved first file to the first user session. The user, via a second user session executing simultaneously with the first user session, issues a request to the server agent for the first file and a second file of the user profile. Upon receiving the request, the server agent identifies a modified version of the first file in a provisional user profile, retrieves the modified first file from the provisional user profile and the second file from the base user profile, and just in time delivers both files to the second user session.

Methods and systems for providing a consistent profile to overlapping user sessions

The present invention is directed towards systems and methods of streaming an application from a remote location to a local machine system, and using local machine system resources in executing that application. In various embodiments, services needed by a streamed application may be started with high local system privileges in their own isolation environment. These service may be started, stopped, and otherwise managed by a Service Control Manager. In order for an application to both access services that operate at high local system privileges and the network so that it can access remotely stored, streaming, information; a streaming application may rely on privileges of the user when accessing network information rather than the higher privileges of the services running in isolation.

Encryption-based data access management may include a variety of processes. In one example, a device may transmit a user authentication request for decrypting encrypted data to a data storage server storing the encrypted data. The computing device may then receive a validation token associated with the user's authentication request, the validation token indicating that the user is authenticated to a domain. Subsequently, the computing device may transmit the validation token to a first key server different from the data storage server. Then, in response to transmitting the validation token the computing device may receive, from the first key server, a key required for decrypting the encrypted data. The device may then decrypt at least a portion of the encrypted data using the key.

Encryption-based data access management

Securing encrypted virtual hard disks may include a variety of processes. In one example, a virtual hard disk is created for a user and encrypted with a volume key, and the volume key placed in an administrator header. The administrator header may be encrypted with a protection key, the protection key created from a user identifier corresponding to the user, a volume identifier corresponding to the virtual hard disk, and two cryptographic secrets. The protection key may then destroyed after encrypting the administrator header and therefore, might never leave the encryption engine. The two cryptographic secrets may be stored in separate storage locations, one accessible to the user and the other accessible to administrators. Accordingly, the protection key might never transmitted or can be intercepted, and no single entity may be compromised to gain access to all of the information needed to recreate the protection key.

Systems and methods for service isolation

A technique manages an online meeting. The technique includes providing an audio output signal to a first client device currently participating in the online meeting. The audio output signal directs the first client device to play a particular sound (e.g., a unique tone or a unique series of tones). The technique further involves receiving an audio input signal from a second client device. The audio input signal includes the particular sound. The technique further involves identifying the second client device as being co-located with the first client device in response to the audio input signal which includes the particular sound. Such operation enables the electronic circuitry (e.g., a processing circuit of an online meeting server) to learn whether any client devices are co-located and accordingly associate multiple devices to a single user connected to the online meeting.

Using audio signals to identify when client devices are co-located

A method and system for aggregating installation scopes within an isolation environment, where the method includes first defining an isolation environment for encompassing an aggregation of installation scopes. Associations are created between a first application and a first installation scope. When the first application requires the presence of a second application within the isolation environment for proper execution, an image of the required second application is mounted onto a second installation scope and an association between the second application and the second installation scope is created. Another association is created between the first installation scope and the second installation scope, and this third association is created within a third installation scope. Each of the first, second, and third installation scopes are stored and the first application is launched into the defined isolation environment.
