image - changing least significant bit of a pixel using steganography -

i implementing image encryption algorithm , in 1 phase change least significant bit of pixel. per steganography, there stego-key can used overwrite lsb of pixels. but, how stego-key determined @ receiver end. also, know if changing least significant bit 1 0 or 0 1 considered steganography?

but, how stego-key determined @ receiver end.

key management or encryption not part of steganography. may perform key agreement hiding well, again, steganography hiding of information. encryption may used let message appear random adding additional layer of security though. data appears random may easier hide.

see following definition wikipedia:

the practice of concealing messages or information within other non-secret text or data.

also, know if changing least significant bit 1 0 or 0 1 considered steganography?

that case yes. note if have blue background message still visible - if encrypted random changes. in general, if chances of least significant bit being set more or less random, make prime candidate steganography.

you might question how many times raw rgb (or whatever other lossless format) exchanged, pixels more or less random. in considered hint strange going on. long try hide message still called steganography though.
