    Abstract: A variety of techniques for performing identity verification are disclosed. As one example, a verification request is received from a remote user. The verification request pertains to a cryptographic key. In response to receiving a confirmation from a local user of the local device, a verification process is initiated. A result of the verification process is transmitted to the remote user. As a second example, a verification request can be received at the local device, from a local user of the device. A verification process with respect to the local user is initiated, and a result of the verification process is transmitted to a remote user that is different from the local user.

    Abstract: Determining whether to allow access to a message is disclosed. A message is received from a sender. The message is associated with a first time-to-live (TTL) value. A determination is made that the first time-to-live value has not been exceeded. The determination is made at least in part by obtaining an external master clock time. In response to the determination, access is allowed to the message.

    Abstract: A first public key associated with a first recipient is requested from a server. The first public key is received, as is an associated first key reference value. The first public key is used in conjunction with securing a first message. The first public key is destroyed. A second public key associated with the first recipient is requested from the server. A second public key and an associated second key reference value are received. The second public key is different from the first public key and the first key reference value is different from the second key reference value. The second public key is used in conjunction with the securing of a second message and the second public key is destroyed.

    Abstract: The present disclosure describes techniques for storing encrypted files in a secure file repository and transferring those encrypted files to one or more recipients. A user selects a file to upload to a secure file repository. A secure collaboration app on the user's device generates a first encryption key that is used to encrypt the file. The encrypted file is then uploaded to the secure file repository, which provides the secure collaboration app with a random file name and a location of the encrypted file. The secure collaboration app updates locally stored metadata of the first encrypted file. To securely transfer the file, the user generates a second encryption key, encrypts the metadata with the second encryption key, and transmits the encrypted metadata to one or more receivers. The one or more receivers decrypt the encrypted metadata and use the decrypted metadata to retrieve the file and decrypt it.

    Abstract: Secure directory services are disclosed. A cryptographic hash of a foreign identifier associated with a potential user is received. A determination is made that the received cryptographic hash of the foreign identifier matches a representation of a stored entry. In response to the determination, a transmission of a representation of a native identifier associated with the stored entry is transmitted to the sender of the cryptographic hash of the foreign identifier.

    Abstract: Determining whether a message should be allowed to be sent is determined. A request to send a message to a recipient is received from a sender's client device. A determination is made at a server as to whether the sender is allowed to send the message to the recipient, based on a privacy list. A response to the sender is sent, based on the determination.
