    Abstract: A method and an apparatus for estimating a geometric thickness of a breast in mammography/tomosynthesis or in other x-ray procedures, by imaging markers that are in the path of x-rays passing through the imaged object. The markings can be selected to be visible or to be invisible when the composite markings/breast image is viewed in clinical settings. If desired, the contribution of the markers to the image can be removed through further processing. The resulting information can be used determining the geometric thickness of the body being x-rayed and thus setting imaging parameters that are thickness-related, and for other purposes. The method and apparatus also have application in other types of x-ray imaging.

    Abstract: Aspects of the present disclosure relate to systems and methods for exchanging keys within a peer-to-peer network. Exchanging keys within a peer-to-peer network may include generating one or more keys for encrypting and decrypting content that is communicated between one or more client computing devices of a network. The one or more keys may be transmitted over the peer-to-peer network between the one or more client computing devices. A security measure value for each key that has been transmitted may be generated and/or updated based on at least one condition associated with transmitting the one or more keys over the peer-to-peer network. Content may be encrypted and decrypted using one of the one or more keys based on a desired security measure value of the key. All copies of the key used to encrypt and decrypt the content may be deleted such that the content is unrecoverable.

    Abstract: Illustrative implementations are described for an automated email message and document shredding system. The implementations provide for generating electronic content and associating the content with a condition upon which the content may self-terminate. Based on the condition, a security context may be determined for the content. The security context determination facilitates the association of a security key corresponding to the security context associated with the content. The security key may be applied to the content to generate encrypted content. A notification of the security key used to encrypt the content, a notification of the condition upon which the content will self-terminate and the encrypted content may then be transmitted to a recipient.
