A method is disclosed for quarantining digital content data for a service in a terminal device. In an embodiment, the method includes creating a digital content data item, e.g. a digital still image or a video stream, in the memory of the terminal device, generating a symmetric encryption key for encrypting the created digital content data item, encrypting the digital content data item using the generated symmetric encryption key, encrypting the generated symmetric encryption key using public key of the service, deleting the unencrypted version of the digital content data item and of the symmetric encryption key from the memory of the terminal device, sending the encrypted version of the digital content data item and of the symmetric encryption key to a server of the service, and receiving from the server of the service at least one of the following: instruction to delete the encrypted digital content data item from the memory of the terminal device, and decrypted version of the symmetric encryption key for decrypting the encrypted digital content data item in the memory of the terminal device.
