EXHIBIT 31.1


                                  CERTIFICATION

      I, John Mahoney, 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 annual 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-14(c) and 15d-14(c)) 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)    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.
