Embodiment

[0050] Anti-counterfeiting protection for the original sample file qhb25.xy:

[0051] The steps to embed a watermark are:

[0052] 1. Open the original sample file qhb25.xy;

[0053] 2. Click the Load Watermark button, and a dialog box will pop up asking the user to input any character watermark information;

[0054] 3. Convert the watermark information input by the user into a string of binary 0-1 strings through the ASCII code of the characters, and save the correspondence between the 0-1 strings and the original watermark information;

[0055] 4. Traversing each organization point of the sample file, the point with the most occurrences is the organization point, thereby determining the organization information of the organization point;

[0056] 5. Traversing to find optional watermark points, as long as it is a point at the junction of continuous latitude segments, it is considered optional. The continuity here defaults to the span of the latitude segment being at least ...

Abstract

The utility model discloses an anti-counterfeit method which adopts watermark technology aiming at multilayer wave weft, which comprises embedding water mark and withdrawing water mark; wherein the embedding water mark comprises the following steps: 1). Optional water mark point, which is suitable for weft appearance requirements, is searched among original small sampling document; 2). Optional water mark point is judged whether to be in conformity with balance requirements of weft tension; 3). Optional water mark point suiting for requirements are coded and water mark information is embedded; withdrawing water mark comprises the following steps: 1). Each tissue point of original small sampling document is compared currently to identify different tissue point which is a water mark point; 2). Converse coding is made for the water mark point to get water mark information. Based on analyzing production process and anti-counterfeit requirement of figured cloth, the minimizing coding proposal is adopted by the utility model. Through computer simulation and production site experiment, the method is proved effective and practical; the utility model has the advantages that the difficulty and cost of forger are increased and own brand pattern of the multilayer wave figured cloth can be effectively protected.

Description

technical field [0001] The invention relates to an anti-counterfeiting method using watermark technology for multi-layer tissue fabrics. Background technique [0002] Textile fabrics are necessary daily consumer goods, and their value consists of various factors such as materials, patterns, and workmanship. Anti-counterfeiting of textile fabrics, the most important of which is the protection of patterns. Famous brands have an urgent need for design protection in the fierce market competition. However, the actual protection methods in the textile industry are very limited at this stage, mainly because the protection measures are strictly restricted by various preconditions. These constraints include limitations on the appearance of fabric patterns, limitations on cost, and limitations on various production processes. At present, electronic technology and computer technology have been widely used in the textile field, such as electronic jacquard bridle and computer loom are...
