Problem Statement: 

                 Further to as published or illustrated or examplified else-where 
                 in the document referred below viz. projects.pdf or as published 
                 else where by this individual ...


          unix 'touch' as a utility ...potential possibilities and scope of the data,

          viz. scope for doctoring of the data as also manipulation of the data
               ...thus given the room and scope for legitimacy of the data ??


               This individual also has amply exemplified perils and scope of using
               computing environments...

Opportunity:  In stead of using re-writable mediums ...as existing both tape based
              or optical disk based  or magnetic disk based.


              understanding from the scope of how a 'X-ray' / photo-negative(refer to
              reel or exposure light based carbon strips ...non re-coatable ...use
              and throw or specifically single use) works     


              innovative mediums tape base or disk based ...which work based on exposure
              to light (termed radio-active or ultra-voilet) ...which are only write-once
              and ready many times.

              as illustrated or scope exemplified in the document projects.pdf and else-where
              by this author ...viz. recording transactions on to a tape based mediums (given 
              that most support high speed volume as existing in market these days)

              ...understanding from how a plex or concepts of multiplexing or usually a
              concept used at micro-code level or device driver level where in data is
              buffer to both the mediums viz. where in data

              can be recorded both on a tape based medium as also a magnetic disk medium,

              while magnetic disk based mediums high speed data access ...the vulnerabilities
              as described above and can be envisioned (applying use-case modelling)
              ...could potentially be circumvented using standard backup and restore practices
              put in place ..and as envisoned in some popular softwares like (ex-change servers
              or RDBMS servers) ... to keep the data authentic and concurrent and valid.

         
             
 Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      
       http://uk.geocities.com/ravivenkatus/projects.pdf
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
