    Question how to convert structure disorganization of a VIDEO file and or RAR file to FASTQ

    i read text of FASTQZ algorithm for fastq file by dear matt mahoney
    i have a question
    how to convert structure with disorganization of a VIDEO (as .flv) file and or RAR file to
    FASTQ (output of DNA sequencing machines) ?

    i also see bitcasa and exdupe project and i think there are any solution for reduce of file size by bit wise operations
    are there any idea ?
    sorry for bad english knowledge

    it's pretty obvious. just recognize people in the video and encode their DNA

    Yeah, that 's probably the best you can do

    Really, video would be a separate algorithm. For RAR, just extract it and compress it again with paq8px.

    dear masters tnq for your answers

    nosso compressor on nosltd.com
    bitcasa on cloud service
    and exdupe projects

    i think these projects used algorithm of bit wise method for reduce radically of file size
    which algorithm (or algorithms ) used these project ?
    maybe you say your guess of how to work this projects ?

    Fastqz algorithm is described in https://docs.google.com/document/pub...1Aet902dA8QZZk

    zpaq is described in this section of my book: http://mattmahoney.net/dc/dce.html#Section_437

    Bitcasa reportedly uses Convergent Encryption:

    The basic form of convergent encryption is taking your original file and calculating a hash from it. Then using this hash as the key, you encrypt the rest of the file. Finally using your password, you encrypt this hash key and store it somewhere else. This means the only way to get the password of the file is by owning the original file. If bill and ted both have the same file, they will both calculate the same hash, and the same encrypted file. Therefore since the encrypted version is the same, you only need one copy. To decrypt the file, you first decrypt the hash using your password, then the decrypt the file using the hash.
