Taiwan-based startup BlockChain Security has launched Blockchain Witness app for preserving digital data as evidences for legal purposes, according company CEO Po Huang.
While digital files are easy to be lost and falsified, Blockchain technology can preserve digital data to make them non-repudiable and tamper-proof, and matched with digital fingerprinting technology it can ensure the authenticity and validity of evidences, Huang said.
Blockchain Witness can take photos, record video or voice, take screen shots and then upload them in virtual blocks for digital evidence preservation, Huang noted, adding the app is equipped with GPS to track the time and location of the uploaded digital data. For uploading and preservation, BlockChain Security adopts both private and public blockchain, Huang said.
