    • The present invention provides a data compression / decompression device and a method thereof. For this purpose, the present invention: compresses data through encoding after hiding the information thereof, extracts hidden information from decoded data after decoding a compressed packet, and restores binary data. Furthermore, the present invention provides a structure for converting the data with hidden information into a binary code, a compression method for encoding and packing the binary data, and a restoration method for decoding the encoded data that comprises the steps of converting the decoded data into an m-array row information symbol and restoring a binary information bit row from the m-array information symbol row.
    • 本发明提供一种数据压缩/解压缩装置及其方法。 为此,本发明在隐藏其信息之后通过编码来压缩数据,在对压缩包解码之后从解码数据中提取隐藏信息,并恢复二进制数据。 此外,本发明提供了一种将隐藏信息的数据转换为二进制码,用于对二进制数据进行编码和打包的压缩方法的结构,以及用于对编码数据进行解码的恢复方法,包括以下步骤:将解码的数据转换为 m阵列行信息符号,并从m阵列信息符号行中恢复二进制信息位行。
