The Security Foiling blog - 'Foiling the Forgers' - part two

This is the second of four articles focusing on the many uses of Hot Stamping Foils to assist in counterfeit prevention and detection for security documents.

‘Foiling the forgers’ – The Foiled security image – the ‘authentication’ challenge

    Considering any type of security feature to a document should always provoke a discussion about authentication – how do you know the feature is genuine? can you check?....what type of checking is practical for this document?

    As with all document security features; hot stamping foil (HSF) authentication features can have up to three means of authentication.

    Level One – Visual feature such as colour change that requires no ‘tools’ to check

    Level Two – Features that require the use of ‘tools’ such as microtext magnification, screen reveal slides, hidden features revealed by laser pens etc.

    Examples below; firstly Security Foiling's DUOGRAMHD feature revealing 'OK' at a specific viewing angle - requires no special tools and is a Level One feature. The second image requires back lighting to reveal hidden information, in this image Security Foiling's 'Thru-View technology is revealed by a smartphone flashlight and would be a Level Two feature.

    Level Three – Forensic features that require extensive laboratory testing and possible destruction of the document

    The design of the HSF security feature must recognize the customers needs and how they may use the feature in practical terms. 

    Level One features remain the primary method of validating documents often due to time constraints in checking documents (concert and sporting event ticketing requiring quick movement of crowds into the venue). 

    Level One features are almost always combined with Level Two & Three features. Higher level authentication methods may only be used when documents are ‘questioned’ – this allows more time for that document to be checked more thoroughly (typical in border control applications or government investigation bureaus) in a controlled environment. The HSF feature will be one part of a more thorough document examination and may act as an early detection device of a document being suspicious.

    In the third article, we will look at 'Personalizing’ – adding unique features to hot stamping foil and holograms
