Audio redaction is the process of editing or removing sensitive information from audio recordings before they are shared or disclosed. Various laws and regulations require the protection of personal information in audio recordings.
Whenever an audio recording contains an individual's PII, it may be necessary to redact it to comply with privacy regulations.
#Compliance requirements for audio redaction
Key compliance requirements are different for organisations in different industries and depending on their locations, and include regulations such as the General Data Protection Regulation (GDPR), other European rules and regulations, FOIA requirements, and FERPA requirements for US educational institutions.
Certain types of information must be redacted from audio recordings to protect privacy. These include personally identifiable information (PII), such as names, addresses, phone numbers, social security numbers, driver's licence numbers, medical records and other identifying details, as well as confidential information.
Failure to properly redact audio recordings may lead to legal consequences, financial penalties and reputational damage.
#Examples of audio redaction types across industries
Retail
Retailers capture details of customer transactions, staff conversations or payment details in CCTV or bodycam footage, plus personally identifiable information during in-store accidents. They may need to be redacted to provide incident footage, as a response to SARs or requests from insurance or law enforcement agencies, or when using footage for training.
Healthcare
Hospitals and clinics record interactions across wards, reception areas and other spaces. When a data subject access request arrives, healthcare providers must redact all third-party PII before releasing footage, including, for example, a patient's spoken medical history or conversations conducted with the security staff that disclose names or other PII.
Identity Cloak allows NHS trusts and private healthcare providers to redact both the video (blurring faces or sensitive environments) and the audio (muting overheard conversations).
Education
Schools, colleges and universities use CCTV and audio surveillance to monitor student safety. Audio redaction ensures only the relevant information is used for resolving safety concerns while protecting the privacy of students and staff.
Local governments
Government agencies record public hearings, enforcement interactions and facility surveillance. They may receive SARs and footage requests for legal proceedings.
Transportation and Logistics
Transport and logistics operators capture vast amounts of footage from dashcams, on-board CCTV and depot cameras. This footage frequently includes audio. It may be requested for insurance claims, accident investigations or regulatory reviews.
Venues and museums
Museums, galleries, entertainment venues and private clubs operate CCTV networks across public galleries, gift shops, event spaces, and staff-only areas. Audio captured in these environments can include visitor conversations, membership details discussed at reception desks, private event proceedings and staff interactions.
This footage may be requested for insurance claims, incident investigations or SARs.
#Identity Cloak for video and audio redaction
Facit's Identity Cloak is a desktop redaction application that handles both video and audio redaction. Rather than exporting audio separately or relying on a third-party audio editor, users can redact the audio track directly inside Identity Cloak.
#Audio redaction features in Identity Cloak
Users can mute specific portions of the audio track, whether that's a spoken name, an address read aloud or healthcare information shared in a hospital.
#Redact audio from any source
Identity Cloak processes audio captured from bodycams, dashcams, CCTV, and mobile phone footage. If a video file contains an audio track, Identity Cloak can redact it.
#Combine audio and video redaction
Instead of running two separate tools, you can blur faces, licence plates and bodies in the video while also redacting the audio track.
#Trim videos before starting video redaction
Users can trim footage to include only the relevant section before redacting audio, which cuts down review time and ensures only necessary content is released.
#Process footage on-premise
Like all Identity Cloak operations, audio redaction happens locally on your device behind your firewall. No data is uploaded to external servers, which reduces the risk of data breaches.
#Keep the original file intact
The source file remains untouched. Identity Cloak generates a new, redacted export in MP4 or AVI format, maintaining a clear audit trail between the original and the redacted version.
#Identity Cloak in action: case studies
Facit's Identity Cloak is trusted by organisations in 23 countries to redact video and audio footage. Here are examples of how real organisations use the software — including its audio redaction capabilities — to stay compliant.
#King's College Hospital NHS Foundation Trust
King's College Hospital is one of London's largest and busiest teaching hospitals. The Trust needed to fulfil SARs and comply with data privacy regulations without depleting budgets or wasting resources on administrative tasks.
It uses Identity Cloak to process different types of footage, including body-worn devices.
“The application sits within our own network, which ensures that the Trust’s video never leaves our own secure environment, rather than having to place our video in the Cloud, which was an issue here at the Trust.
Ian Taylor Head of Security, King's College Hospital NHS Foundation Trust
#Córas Iompair Éireann (CIÉ)
Córas Iompair Éireann (CIÉ), Ireland’s state-owned public transport group, deployed Identity Cloak to process videos in-house instead of outsourcing them. An additional reason to choose Identity Cloak was anticipating new types of redaction challenges, including AI-generated meeting recordings that would require a new approach.
“Identity Cloak is a winner for us. I’m totally happy with what it does and how it does it.”
Paul Whelan, Data Protection Officer (DPO) at CIÉ
#River Island
River Island, a London-based, multi-channel fashion brand with 300+ locations across the UK, chose Identity Cloak to manage CCTV footage in a compliant manner. The company also wanted to be prepared for changes in surveillance approaches in the future, such as redacting bodyworn cameras and audio tracks.
“As our needs change it’s good to know that our compliance software is ahead of emerging requirements. Identity Cloak isn’t just a piece of software, it’s essential in ensuring we meet our obligations to our customers, our staff and the law.”
Jenny Jones, Pensions Administrator at River Island
