Peter Prater has spent eight years perfecting his product.
A Gloucestershire entrepreneur has invented a machine which he claims will help cut down on breaches in data protection.
Peter Prater from Dursley has spent eight years perfecting the piece of technology which he says will protect people's private information from falling into the wrong hands.
The piece of equipment known as Cypherseal securely seals documents ready to post after they have been printed from a PC.
The company claims it is the only secure print mailing machine to print and seal mail in a completely tamper evident way.
Peter said: "I was determined to address the growing challenge of protecting personal information like credit card data and medical information and keen to give businesses and public sector organisations an opportunity to fight back.
"People nowadays need peace of mind that confidential mail like bills, medical letters and financial statements cannot be opened and resealed.
"Cypherseal mail is unique because no-one other than the recipient can open the envelope without it showing signs that it has been tampered with.
"Unlike Cypherseal, traditional post can be left lying on the printer for everyone to see and can be opened after posting and put into another envelope while the recipient is unaware that their personal information has been revealed."
In April 2010 new rules came into effect meaning companies that breach the Data Protection Act can be fined up to £500,000 for serious offences.
