**CERTIFICATION**





I,
      Philip
      Jones, certify that:





1.  I
      have
      reviewed this quarterly report of Form 10-Q of Document Security Systems,
      Inc.;





2.  Based
      on
      my knowledge, this quarterly report does not contain any untrue statement of
      a
      material fact or omit to state a material fact necessary to make the statements
      made, in light of the circumstances under which such statements were made,
      not
      misleading with respect to the period covered by this quarterly
      report;





3.  Based
      on
      my knowledge, the financial statements, and other financial information included
      in this quarterly report, fairly present in all material respects the financial
      condition, results of operations and cash flows of the registrant as of, and
      for, the periods presented in this quarterly report;





4.  The
      registrant’s other certifying officer and I are responsible for establishing and
      maintaining disclosure controls and procedures (as defined in Exchange Act
      Rules
      13a-15(e) and 15d-15(e)) and internal control over financial reporting (as
      defined in Exchange Act Rules 13a-15(f) and 15(d)-15(f), for the registrant
      and
      we have:





a)  
      Designed such disclosure controls and procedures or caused such disclosure
      controls and procedures to be designed under our supervision, to ensure that
      material information relating to the registrant, is made known to me by others
      within the company, particularly during the period in which this quarterly
      report is being prepared;





b)  
      Evaluated the effectiveness of the registrant's disclosure controls and
      procedures and presented in this report our conclusions about the effectiveness
      of the disclosure controls and procedures, as of the end of the period covered
      by this report based on such evaluation;





c)  
      Disclosed in this report any change in the registrant’s internal control over
      financial reporting that occurred during the registrant’s most recent fiscal
      quarter that has materially affected, or is reasonably likely to materially
      affect, the registrant’s internal control over financial reporting;
      and





5.  The
      registrant’s other certifying officer and I have disclosed, based on our most
      recent evaluation of internal control over financial reporting, to the
      registrant’s auditors and the registrant’s audit committee of the board of
      directors (or persons performing the equivalent functions);





a)  
      All significant deficiencies and material weaknesses in the design or operation
      of internal controls over financial reporting which are reasonably likely to
      adversely affect the registrant’s ability to record, process, summarize and
      report financial information; and





b)  
      Any fraud, whether or not material, that involves management or other employees
      who have a significant role in the registrant’s internal controls over financial
      reporting;
