Data compression method, electronic device and computer program product

An electronic device, comprising:

• a processor;
• and
• a memory coupled to the processor and having instructions stored therein, wherein the instructions, when executed by the processor, cause the device to execute actions comprising:
• selecting, from a data block, a plurality of bit strings as sample data;
• determining a set of characters comprised in the sample data, each character among the set of characters being represented by at least one bit string among the plurality of bit strings;
• and
• compressing the data block if statistical characteristics of the set of characters match predetermined statistical characteristics.

A computer program product having a non-transitory computer readable medium which stores a set of instructions to perform data compression;

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• selecting, from a data block, a plurality of bit strings as sample data;
• determining a set of characters comprised in the sample data, each character in the set of characters being represented by at least one bit string among the plurality of bit strings;
• and
• compressing the data block if statistical characteristics of the set of characters match predetermined statistical characteristics.
