To ensure the confidentiality and security of audio and video files sent for transcription, when required, Word Works has a number of different tools and security measures that can be implemented, including: The use of encryption software: files are encrypted using encryption software to prevent them from being accessed by unauthorised third parties. Restricted access to files: only authorised transcribers have access to files and they are required to sign a confidentiality agreement. Secure deletion procedures: once the transcription is completed, the original files and all copies are securely deleted, when requested by the customer in advance. Network protection: network security measures are used to prevent unauthorised access to files, including firewalls and network security software.
