 CERTIFICATION
        PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002
 I,
          Stephen D. Barnhill, certify that:
 
 1.  I
          have reviewed this
          quarterly report on Form 10-QSB of Health Discovery Corporation (the
“Registrant”);
 
 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 officers and I are responsible for establishing and maintaining
          disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e))
          and internal controls over financial reporting (as defined in Exchange
          Act Rules
          13a-15(f)) for the Registrant and 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, including its consolidated subsidiaries, is made known
          to us by
          others within those entities, particularly during the period in which this
          report is being prepared;
 
 b)  designed
          such internal controls over financial reporting, or caused such internal
          controls over financial reporting to be designed under our supervision,
          to
          provide reasonable assurance regarding the reliability of financial reporting
          and the preparation of financial statements for external purposes in accordance
          with generally accepted accounting principles;
 
 c)  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 the end of the period covered by
          this
          report based on such evaluation; and
 
 d)  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 (the
          Registrant’s third fiscal quarter in the case of this report) that has
          materially affected, or is reasonably likely to materially affect, the
          Registrant’s internal control over financial reporting;
 
 5.  The
          Registrant’s other
          certifying officers and I have disclosed, based on our most recent evaluation
          of
          internal control over financial reporting, to the Registrant’s auditors and the
          audit committee of Registrant’s board of directors (or persons performing the
          equivalent functions):
 
 a)  all
          significant
          deficiencies in the design or operation of internal control 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 control over financial
          reporting.
