Abstract
There is disclosed in an example a computing apparatus, comprising: a network interface; a messaging application to communicate via the network interface; and one or more logic elements comprising a security layer, discrete from the messaging application, to: generate a message; secure the message; and send the message via the messaging application.
Claims18
A computing apparatus, comprising:
- a processor and memory;
- a network interface;
- a messaging application to communicate via the network interface;
- and
- instructions stored on the memory and configured to instruct the processor to provide a security layer comprising a third-party security-aware software keyboard different from an operating system-provided keyboard and discrete from the messaging application, the security layer configured to:
- generate a sensitive message from user input to the third-party software keyboard;
- secure the sensitive message, comprising encrypting the user input into an encrypted message, and embedding the encrypted message into a dummy conveyor element via steganography;
- and
- send the secured message via the messaging application, comprising sending a multimedia text message with the conveyor element as an attachment, wherein the conveyor element is a digital file, a video file, or a multimedia file.
A computing apparatus, comprising:
- a storage;
- a processor and memory;
- a network interface;
- a networking application to communicate via the network interface;
- and
- instructions stored on the storage and configured to instruct the processor to provide a security layer comprising a third-party security-aware software keyboard different from an operating system-provided keyboard and discrete from the networking application, the security layer configured to:
- receive an incoming sensitive message via the network interface, the incoming sensitive message comprising a steganographic image, wherein the steganographic image comprises an encrypted message from user input to the third-party software keyboard;
- secure the sensitive message, comprising storing the encrypted message from user input on the storage, and embedding the encrypted message into a dummy conveyor element via steganography, wherein the conveyor element is embedded into a multimedia text message with the conveyor element as an attachment, wherein the conveyor element is a digital file, a video file, or a multimedia file;
- detect the stored encrypted message on the storage;
- reverse the steganography;
- and
- decrypt the encrypted message.
One or more tangible, non-transitory computer-readable storage mediums having stored thereon executable instructions to provide a security layer comprising a third-party security-aware software keyboard different from an operating system-provided keyboard and discrete from a messaging application, the security layer configured to:
- generate a sensitive message from user input to the third-party software keyboard;
- secure the sensitive message, comprising encrypting the user input into an encrypted message, and embedding the encrypted message into a dummy conveyor element via steganography;
- and
- send the secured message via the messaging application, comprising sending a multimedia text message with the conveyor element as an attachment, wherein the conveyor element is a digital file, a video file, or a multimedia file, wherein the messaging application is operable to send the sensitive message via a network interface.
