What is a WSQ file?

WSQ files mostly belong to Cabrillo WSQ Viewer. WSQ files are Wavelet Scalar Quantization compressed fingerprint images.
They use a specific compression algorithm that reduces file size while keeping vital fingerprint details. This format is common in biometric and forensic systems.

• The file stores fingerprint data using a wavelet-based compression method.
• It is optimized to preserve minutiae and other distinguishing features.
• Standard image viewers often cannot open WSQ files.
• Specialized tools like Cabrillo WSQ Viewer or WSQ Decoder are used to view and process these files.

WSQ file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our examination of the WSQ files comes to the following conclusion:

Files with the WSQ extension are quite widely used. This file type predominantly uses a uniform format. The following file formats are most commonly found in WSQ files:

• 75% of all WSQ files are Wavelet Scalar Quantization bitmap files. These files contain neither text nor words, but only data. The files are often between 7 KB and 37 KB in size. This file type is based on cutting-edge technology. The following keywords are characteristic: COLORSPACE GRAY, COMPRESSION WSQ, HEIGHT, WIDTH, LOSSY 1, PIX_DEPTH 8, PPI 500, WSQ_BITRATE 0.750000 and zNIST_COM 9. The following filename is common: sample_image.wsq. Files like these have the following tags: image, finger, right, left, sample, index, thumb, compressed, direito and anular.
• 3% of all WSQ files have the same signature 2F 36. The contents of these files can even be read by a human. WSQ files are between 5 KB and 72 KB in size. Several words can almost always be found in the files, e.g. TklTVF, gOQpQSVhfV, ERVBUSCA, MDAKTE, NRCldTUV, NUFJFU, kgMQpDT, xPUlNQQUNFIEdSQVkKQ and ClBQSSA. test.wsq is a typical file name.

The remaining 22% of all WSQ files are different files with different signatures, often e.g. JFIF. Often described as fingerprint, digital, print, leftindex, exported, little, data or hola. Just click the "Choose your .wsq file to analyze" button on this page to find out what your WSQ file is.
