发明名称 Forbedret integritetsbrudd-avslörende blankett
摘要 Confidential information is printed on an upper transparent laminate. A scrambling pattern is associated with a lower laminate. The upper surface of the lower laminate and the lower surface of the upper laminate are complementary in shape such that the upper laminate appears transparent, but alters to appear translucent when separated from the lower laminate. This provides a tamper-evident mechanism for indicating separation of the laminates.
