     CERTIFICATION PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Emilian Elefteratos, Chief Executive Officer of SiVault Systems, Inc.,
certify that:

1. I have reviewed this quarterly report on Form 10-QSB of SiVault 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)) 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, including
      its consolidated subsidiaries, is made known to us by others within those
      entities, 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 quarterly 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 our evaluation;

      c) Disclosed in this report any change in the registrant's internal
      controls over financial reporting that occurred during the registrant's
      most recent fiscal quarter (the registrant's fourth fiscal quarter in the
      case of an annual report) 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, on our most
   recent evaluation of internal controls over financial reporting, to the audit
   committee of registrant's board of directors (or persons performing the
   equivalent functions):

      a) All significant deficiencies and material weaknesses 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.

6. Management has not yet performed, and is not yet required to perform, its
   assessment of the effectiveness of internal control over financial reporting
   as required by Section 404 of the Sarbanes-Oxley Act of 2002.
