A proprietary format for digital images not universally readable in image viewers.

The process of converting raw picture data into a viewable image format.

Exchangeable Image File Format, a standard for storing metadata in JPEG and TIF files.

Data that provides information about other data, including camera details and settings.

A standard header for JPEG files starting with hexadecimal value FFE0.

A program used to view metadata in EXIF JPEG files.

Location data recorded by cameras with GPS capability in the EXIF metadata.

Includes shutter speed, focal length, and resolution of an image stored in EXIF.

The process of coding data from a larger to a smaller form to save space.

A method that reduces file size without deleting any data.

A method that compresses data by permanently removing some information.

An image format that uses lossless compression to save file space.

A graphics format that uses lossless compression, preserving quality.

An algorithm used in lossless compression to reduce file sizes by coding.

An algorithm for lossless data compression, reducing redundancy.

A common lossy image format that reduces file size by discarding data.

File formats that forensic tools do not recognize or are uncommon.

Information at the beginning of graphic files that helps identify the format.

A tool used to view and edit the hexadecimal values of files.

The practice of hiding information within other files, such as images.

Techniques that hide data within the structure of a file without showing it.

Technique of replacing bits in a file with other bits, minimally altering the file.

Software that opens and displays graphic files.

A specific sequence of hexadecimal values used to identify a file format.

Graphics that store calculations for drawing lines and shapes, allowing scalable images without quality loss.

Graphics that store image data in pixels, often losing quality when enlarged.

Graphics combining raster (bitmap) and vector graphics, sharing pros and cons of both.

Common file formats for bitmap graphics include PNG, GIF, JPEG, TIFF, BMP.

Common file formats for vector graphics include HPGL, DXF, EPS, WMF, EMF.

When a bitmap image is enlarged, it loses quality, appearing pixelated or blurry.

Vector images can be enlarged without losing any quality or becoming pixelated.

Software tools used for creating and editing vector and bitmap graphics, like Microsoft Paint and Adobe.

A file type where each pixel is represented by 8 bits of color data.

The first bit in a binary number, affecting value the most.

The last bit in a binary number, affecting value the least.

Software used to detect hidden data within files.

A method of embedding copyright information into a digital file.

Legal regulations protecting creators' rights over their works.

Creative works eligible for copyright protection, like literature or art.

A header of a file that has been partially overwritten, making it unreadable.

A number system using base-16, essential for identifying file formats.

The unique hexadecimal values that identify a JPEG file, starting with FFD8.

Areas of a storage device that have not been assigned to any active file.

An incorrect identification of a file or data that doesn't actually exist.

The splitting of a file into pieces that are not stored sequentially.

The process of correcting and reconstructing the header of a compromised file.

Finding and exporting the small segments of a fragmented file to its original form.

The process of determining unknown graphics file formats.

A known good file header used as a reference for comparison in repairs.

The act of moving the identified clusters from a storage device to another location for recovery.

The precise numerical codes that need to be inserted to repair a broken file header.

A designated file where recovered fragments are assembled to recreate the original file.

Data recovered from electronic devices that can be used in investigations.
